Release notes
=============
This file describes changes in recent versions of Modules. It primarily
documents those changes that are of interest to users and admins.
.. _5.3 release notes:
Modules 5.3.0 (not yet released)
--------------------------------
* Add :ref:`module-cache` design notes.
* Add :subcmd:`cachebuild` sub-command to create cache for modulepaths
enabled or specified on the command line. Cache files are named
``.modulecache`` and stored at the root of modulepath directories.
* Add :subcmd:`cacheclear` sub-command to delete cache file in all enabled
modulepaths.
* Use cache file if available rather search the content of modulepath
directories when searching for modules (e.g., during :subcmd:`avail`,
:subcmd:`load`, :subcmd:`display`, etc).
* Script: add cache-enabled version of *avail*, *whatis* and *load* tests on
:command:`mb` benchmark utility.
* Add the :mconfig:`ignore_cache` configuration option to ignore module cache
file. Option is disabled by default and when set, it defines
:envvar:`MODULES_IGNORE_CACHE` environment variable.
* Add :option:`--ignore-cache` command-line switch to enable
:mconfig:`ignore_cache` configuration option and ignore module cache file
for current execution.
* Add :mconfig:`cache_buffer_bytes` configuration option to define buffer size
when reading or writing cache files. Option is set to ``32768`` by default.
When set it defines :envvar:`MODULES_CACHE_BUFFER_BYTES` environment
variable.
* Add :mconfig:`cache_expiry_secs` configuration option that defines the
number of seconds a cache file is considered valid after being generated.
Option is set to ``0`` by default which means cache files never expire. When
option is set it defines :envvar:`MODULES_CACHE_EXPIRY_SECS` environment
variable.
* Modulefiles and directories that are not accessible by everyone are not
recorded in cache file. A *limited access* directive is recorded instead to
indicate these modulefiles have to be tested and directories have to be
walked down to determine what the running user can access.
* Doc: update :ref:`reduce-io-load` cookbook recipe with module cache
description.
* Correctly apply extra tag set when loading a module whose variant has value
automatically set. (fix issue #484)
* Catch collection directory creation error and report appropriate message.
(fix issue #482)
* Fix :mfcmd:`source-sh` and :subcmd:`sh-to-mod` shell alias translation when
used with new *fish* shell version (3.6).
* Install: allow to build Modules from a short-depth git repository. (fix
issue #486)
* Install: ensure git log format is not influenced by user's configuration in
:command:`gitlog2changelog.py`. (fix issue #487)
* Init: fix bash shell completion script to be able to complete full name of
available modules. (fix issue #490)
* Install: move licence name to SPDX format in RPM spec file.
.. _5.2 release notes:
Modules 5.2.0 (2022-11-08)
--------------------------
* Introduce the ``--optional`` option on :mfcmd:`prereq`, :mfcmd:`prereq-all`,
:mfcmd:`depends-on` and :mfcmd:`always-load` modulefile commands. Expressed
optional dependency is considered satisfied even if modulefile is not
loaded. If optional requirement is loaded afterward, dependent module is
automatically reloaded, unless if the :mconfig:`auto_handling` configuration
option is disabled.
* A dependency expressed in modulefile with :mfcmd:`module try-load<module>`
command is considered optional. Dependent module is automatically reloaded
if the optional requirement is loaded afterward, unless if the
:mconfig:`auto_handling` configuration option is disabled.
* Raise error in case of unknown or misplaced option set on :mfcmd:`prereq`,
:mfcmd:`prereq-all`, :mfcmd:`depends-on` or :mfcmd:`always-load` modulefile
commands.
* Add the :option:`--timer` command-line switch to report the total execution
time of the :command:`module` command. Also report the execution time of
every internal procedure calls when mixed with :option:`--debug` option.
* Init: move :envvar:`PATH` setup (to locate Modules' binaries location) from
shell initialization scripts to the :subcmd:`autoinit` sub-command. (fix
issue #462)
* Init: move :envvar:`MANPATH` setup (to locate Modules' man-pages) from
shell initialization scripts to the :subcmd:`autoinit` sub-command. (fix
issue #462)
* Init: move shell completion setup from shell initialization scripts to the
:subcmd:`autoinit` sub-command. (fix issue #462)
* Enclose installation path references in shell code produced by
:subcmd:`autoinit`, in initialization scripts and Makefiles to guaranty
correct evaluation in case these paths contain a space character. Note that
the quarantine mechanism is not compatible with such installation paths.
* Fix :mfcmd:`source-sh` and :subcmd:`sh-to-mod` when used with *fish* shell
script if ``regex-easyesc`` fish option is enabled. (fix issue #463)
* Add the :mconfig:`protected_envvars` configuration option to define a list
of environment variables that cannot be modified by modulefile commands.
When set, :mconfig:`protected_envvars` defines
:envvar:`MODULES_PROTECTED_ENVVARS` environment variable. (fix issue #429
with contribution from Adrien Cotte)
* Introduce the :subcmd:`lint` sub-command to statically analyze syntax of
modulefiles, modulerc and global/user rc. (fix issue #451)
* Add the :mconfig:`tcl_linter` configuration option to define the program
used to analyze files with :subcmd:`lint` sub-command. This option is set to
``nagelfar.tcl`` by default. When changed from default value, the
:envvar:`MODULES_TCL_LINTER` environment variable is defined. Default value
can be changed with :instopt:`--with-tcl-linter` and
:instopt:`--with-tcl-linter-opts` installation options.
* Add the :instopt:`--enable-nagelfar-addons` installation option (enabled by
default) to install specific syntax databases and plugins to lint
modulefiles, modulerc and global/user rc with `Nagelfar`_. These files are
installed in the directory designated by the :instopt:`--nagelfardatadir`
(``DATAROOTDIR/nagelfar`` by default).
* Doc: add :ref:`lint-sub-command` design notes.
* Install: use :command:`install` command rather :command:`cp` or
:command:`mkdir` to install Modules and guaranty consistent permission modes
on deployed files.
* Also unset :mfcmd:`pushenv` value stacks on :subcmd:`clear` sub-command.
* Doc: add :ref:`mod-to-sh-sub-command` design notes.
* Introduce the :subcmd:`mod-to-sh` sub-command to translate designated
modulefile(s) into code for specified shell. (fix issue #447)
* Make :subcmd:`source` sub-command accepts modulefile specification as
argument. If argument does not correspond to a file path, search it among
available modulefiles. (fix issue #424)
* Doc: clarify :mfcmd:`set-alias` only define shell alias and not shell
function.
* Add the ability to filter the list of collections returned by
:subcmd:`savelist` sub-command. Filtering pattern is matched in a case
insensitive manner by default.
* Add support for :option:`--starts-with` and :option:`--contains` options on
:subcmd:`savelist` sub-command.
* Highlight all search patterns on :subcmd:`list` sub-command output instead
of only the first one..
* Highlight all search patterns on :subcmd:`savelist` sub-command output.
* Add support for :option:`--all` option on :subcmd:`savelist` sub-command not
to limit result to the collection matching currently defined
:mconfig:`collection_target`.
* Doc: add :ref:`Shell support` section in :ref:`modulefile(4)` man page to
describe how shells support the different kind of environment changes that
can be defined in modulefiles.
* Record during :subcmd:`autoinit` sub-command the initial environment state
in :envvar:`__MODULES_LMINIT`. Enabled modulepaths and loaded modulefiles
through :file:`modulespath` and :file:`initrc` initialization configuration
files are recorded in this new environment variable.
* Add :subcmd:`reset` sub-command to restore initial environment. It takes
recorded environment in :envvar:`__MODULES_LMINIT` and restores it.
* Initial environment is restored when collection name specified on
:subcmd:`restore` sub-command equals ``__init__``.
* When no argument is provided to :subcmd:`restore` sub-command and if
*default* collection does not exist, initial environment is restored.
* Initial environment content is displayed when collection name specified on
:subcmd:`saveshow` sub-command equals ``__init__``.
* When no argument is provided to :subcmd:`saveshow` sub-command and if
*default* collection does not exist, initial environment content is
displayed.
* Add :mconfig:`reset_target_state` configuration option to determine behavior
of :subcmd:`reset` sub-command. When set to ``__init__`` (default value)
initial environment is restored. When set to ``__purge__``, a
:subcmd:`purge` sub-command is performed. Any other value, corresponds to
the name of a collection to :subcmd:`restore`. When set,
:mconfig:`reset_target_state` defines :envvar:`MODULES_RESET_TARGET_STATE`
environment variable.
* Doc: add :ref:`initial-environment` design notes.
* Unload *sticky* modules on :subcmd:`restore` and :subcmd:`reset`
sub-commands to fully set environment in collection or initial state.
* Testsuite: add *lint* testsuite to validate syntax of shell and Tcl scripts
of this project. This testsuite can be invoked with ``make testlint`` or
``script/mt lint``. sh, bash and ksh scripts are checked with `ShellCheck`_
tool and tcl scripts are checked with `Nagelfar`_.
* Update :file:`modulecmd.tcl` code and add Nagelfar inline comments to fix
linter reports.
* Script: add usage message and support for ``-h``/``--help`` option on
:command:`mrel`, :command:`mpub`, :command:`mt`, :command:`mtreview`,
:command:`nglfar2ccov`, :command:`mb` and :command:`mlprof` development
utilities.
* Doc: describe :command:`script/mt` and :command:`script/mb` utilities in
:ref:`CONTRIBUTING` guide.
* Fix `ShellCheck`_ error, warning and info reports over all sh, bash and ksh
shell scripts. (fix issue #470 with contribution from Lukáš Zaoral)
* Init: update profile script for sh-like shells to only source sh or bash
initialization script when BASH environment variable is found set. (fix
issue #473)
* Add :subcmd:`stash` sub-command to save current environment and restore
initial one.
* Add :subcmd:`stashpop` sub-command to restore stash collection then delete
this collection file.
* Add :subcmd:`stashrm` sub-command to delete stash collection file.
* Add :subcmd:`stashshow` sub-command to display stash collection file.
* Add :subcmd:`stashclear` sub-command to delete all stash collection files.
* Add :subcmd:`stashlist` sub-command to list all stash collection files.
* Update :subcmd:`savelist` sub-command to filter out stash collections unless
if :option:`--all` option is set.
* Doc: ensure current user environment does not break logging system in
:ref:`log-module-command` recipe. (fix issue #475)
* Rename the default git branch from *master* to *main* to use inclusive
terminology.
* Mark loaded modules that could benefit from a refresh evaluation in the
:envvar:`__MODULES_LMREFRESH` environment variable.
* Optimize :subcmd:`refresh` sub-command to only evaluate loaded modules that
defines volatile environment changes (shell completion, alias or function).
(fix issue #477)
* Add :sitevar:`modulefile_extra_cmds` hook variable that could be defined in
:file:`siteconfig.tcl` file to define specific commands in modulefile
interpreter context. :sitevar:`modulefile_extra_cmds` is a list of command
name and relative procedure pairs. (fix issue #286)
* Add :sitevar:`modulefile_extra_vars` hook variable that could be defined in
:file:`siteconfig.tcl` file to define specific variables in modulefile
interpreter context. :sitevar:`modulefile_extra_vars` is a list of variable
name and value pairs. (fix issue #286)

* Add the :mconfig:`redirect_output` configuration option to control on *sh*,
*bash*, *ksh*, *zsh* and *fish* shells whether or not the output of the
:command:`module` function should be redirected from stderr to stdout. When
set, :mconfig:`redirect_output` defines :envvar:`MODULES_REDIRECT_OUTPUT`
environment variable.
* Introduce the :option:`--redirect`/:option:`--no-redirect` command-line
switches to supersede the value of the :mconfig:`redirect_output`

:mfcmd:`module unuse<module>` modulefile commands to append back when
modulefile is unloaded the value removed at load time or a specific value
set after this option.
* Add the ``--prepend-on-unload`` option to the :mfcmd:`remove-path` and
:mfcmd:`module unuse<module>` modulefile commands to prepend back when

* Doc: add :ref:`lmod-tcl-modulefile-compat` design notes.
* Introduce the ``add-property``, ``remove-property`` and ``extensions``
modulefile commands for compatibility with Lmod Tcl modulefiles. These
commands are evaluated as a *no-operation* command.
* Introduce the :mfcmd:`prereq-any` modulefile command for compatibility with
Lmod Tcl modulefiles. :mfcmd:`prereq-any` is an alias of :mfcmd:`prereq`
command.
* Produce a clear error message when wrong number of argument is received by
:mfcmd:`prereq` command.
* Doc: describe :mfvar:`ModulesVersion` in *Modules Variables* section in

Lmod Tcl modulefiles. This command aborts modulefile *load* evaluation if
modulefile's name is not fully specified.
* Add the :mfcmd:`prereq-all` modulefile command, alias over the
:mfcmd:`prereq` command which acts as an *AND* operation when multiple
modulefiles are specified.
* Add the :mfcmd:`depends-on` modulefile command, alias over the
:mfcmd:`prereq-all` command for compatibility with Lmod Tcl modulefiles.
* Introduce the ``keep-loaded`` :ref:`module tag<Module tags>` that avoids an
auto-loaded module to get automatically unloaded when its dependent modules
are getting unloaded. Update default :mconfig:`tag_abbrev` configuration
option to add an abbreviation for the new tag (``kL``) and default light and
dark color palettes.
* Add the :mfcmd:`always-load` modulefile command for compatibility with Lmod
Tcl modulefiles. This command loads designated modulefile and applies the
``keep-loaded`` tag to it.
* Add the :subcmd:`load-any` sub-command and :mfcmd:`module load-any<module>`
modulefile command for compatibility with Lmod Tcl modulefiles. This command
loads one modulefile from specified list.
* Add support for ``--not-req`` option on :mfcmd:`module try-load<module>` and
:mfcmd:`module load-any<module>` modulefile commands.
* Doc: add :ref:`magic-cookie-check` design notes.
* Add the :mconfig:`mcookie_check` configuration option that control whether
the magic cookie at the start of modulefile (i.e., ``#%Module`` file
signature) need to get checked or not. When set to ``eval`` the number of
file checks is significantly reduced when walking through modulepaths to
search for modulefiles. Default value for this option is overridden by the
:envvar:`MODULES_MCOOKIE_CHECK` environment variable.

in modulefile.
* Create the ``prestdout`` channel for :mfcmd:`puts` modulefile command to be
able to send content that will be evaluated in current shell session prior
any other content. (fix issue #432)
* Add the :mfcmd:`family` modulefile command for compatibility with Lmod Tcl
modulefiles. This command defines family name as a module alias over
currently loading module and express a conflict over this name to ensure
only one member of a family can be loaded in user environment.
:mfcmd:`family` also defines the :envvar:`MODULES_FAMILY_\<NAME\>` and
:envvar:`LMOD_FAMILY_\<NAME\>` environment variables.
* Doc: add :ref:`reduce-io-load` cookbook recipe.
* Add the ability to filter the list of loaded modules returned by
:subcmd:`list` sub-command. Filtering pattern could be part of module name,
symbolic version or alias and is matched in a case insensitive manner by
default. It could also leverage the :ref:`Advanced module version
specifiers` syntax.
* Add support for :option:`--starts-with` and :option:`--contains` options on
:subcmd:`list` sub-command.
* Doc: add :ref:`shell-completion` design notes.
* Introduce :mfcmd:`complete` and :mfcmd:`uncomplete` modulefile commands to
respectively enable and disable shell completion for a given command name.
*bash*, *tcsh* and *fish* shells are supported.
* Track shell completion changes of *bash*, *tcsh* and *fish* shell scripts on
:subcmd:`sh-to-mod` sub-command and :mfcmd:`source-sh` modulefile command.
* Fix typos found in code, tests and documentation. (contribution from Dimitri
Papadopoulos Orfanos)
* Update the :subcmd:`sh-to-mod` and :mfcmd:`source-sh` mechanisms to support
nested function definition on fish shell.
* Fix the :subcmd:`sh-to-mod` and :mfcmd:`source-sh` mechanisms to correctly
detect functions with a ``_`` character in their name on fish shell.
* Update the :command:`module` shell function definition for sh-kind shell to
enclose the output generated by :file:`modulecmd.tcl` in quotes in order to
pass it to the eval command. This change fixes definition of shell function,
especially when coming from shell script evaluation over the
:subcmd:`sh-to-mod` and :mfcmd:`source-sh` mechanisms. (fix issue #434)
* Fix csh shell alias detection on :subcmd:`sh-to-mod` and :mfcmd:`source-sh`
mechanisms when enclosed in parenthesis. (fix issue #434)
* Include for fish shell environment analysis on :subcmd:`sh-to-mod` and
:mfcmd:`source-sh` mechanisms the private functions defined by evaluated
script, in order to catch all definitions that may be useful for shell
completion.
* Fix the :subcmd:`sh-to-mod` and :mfcmd:`source-sh` mechanisms to correctly
detect empty function on fish shell.
* Script: add :command:`pre-commit` git hook script to help verify if commits
are free of misspellings (with `codespell`_ tool) and trailing spaces.
* Doc: fix typos found in documentation with Aspell utility.
* Doc: describe :ref:`Dependencies between modulefiles` in
:ref:`modulefile(4)` man page. (fix issues #431 and #433)

page to provide for each Modules environment variable the name of the
configuration option that could be used to set the variable with the
:subcmd:`config` sub-command.
* Doc: clarify in :ref:`module(1)` man page that
:envvar:`MODULES_SET_SHELL_STARTUP`, :envvar:`MODULES_SHELLS_WITH_KSH_FPATH`
and :envvar:`MODULES_WA_277` should be set prior Modules initialization to
get taken into account.
* Doc: update :ref:`INSTALL` document to provide the name of the configuration
option linked the installation options.
* Doc: describe in :ref:`module(1)` man page the default value of each
configuration option and linked installation option and command-line
switches.
* Doc: add *Configuration options* section in :ref:`INSTALL` document with a
table summarizing all configuration options and their relative installation
options and environment variables.
* Add the :mfcmd:`pushenv` modulefile command for compatibility with Lmod Tcl
modulefiles. This command sets designated environment variable with
specified value and save the previous value set to restore it when the
modulefile is unloaded. Previous values are saved in a
:envvar:`__MODULES_PUSHENV_\<VAR\>` environment variable.
* Doc: add :ref:`Compatibility with Lmod Tcl modulefile` section in
:ref:`modulefile(4)` man page.
* Update definition of the ``module()`` python function and python
initialization script to explicitly send output to ``sys.stderr`` to get the
ability to catch this content.
* Lib: handle ``sysconf`` error in function implementing the
``initStateUsergroups`` procedure. (contribution from Lukáš Zaoral)
* Introduce the :option:`--tag` option for the :subcmd:`load`,
:subcmd:`try-load`, :subcmd:`load-any`, :subcmd:`switch` sub-commands and
associated :mfcmd:`module` modulefile commands and :mfcmd:`prereq`,
:mfcmd:`prereq-all`, :mfcmd:`depends-on` and :mfcmd:`always-load` modulefile
commands. This new option applies specified tags to the module to load.
* Record tags set to loaded modules with the :option:`--tag` option in the
:envvar:`__MODULES_LMEXTRATAG` environment variable to make this information
persists after module being loaded.
* When saving a collection, record loaded module tags set with the
:option:`--tag` option and those resulting from module load states (like
``auto-loaded`` and ``keep-loaded``). The ``--notuasked`` string previously
used to designate auto-loaded modules in collection is changed into the
``--tag=auto-loaded`` option.
* Introduce the :mconfig:`collection_pin_tag` configuration option, that
records in collection all tags set on loaded modules when enabled. Option is
disabled by default and when set it defines the :envvar:`MODULES_COLLECTION\
_PIN_TAG` environment variable.
* When a collection is saved, its content starts with a ``#%Module5.1`` file
signature if :option:`--tag` option is recorded in it.
* Update the :subcmd:`restore`, :subcmd:`savelist`, :subcmd:`saveshow` and
:subcmd:`is-saved` sub-commands to exclude from result or return an error
when checking a collection expressing a higher Modules version requirement
in its header signature than the one currently in use.
* Doc: describe :ref:`differences between run-command file and modulefile
interpretation<Modulefile and run-command interp diff>` in
:ref:`modulefile(4)` man page.
* Doc: describe :mfcmd:`module` sub-commands available as modulefile Tcl
command for each interpretation context in :ref:`modulefile(4)` man page.
* When loading a module with some extra tags defined through the
:option:`--tag` option, if this module is already loaded the new tags are
added to those already set.
* When reporting result of :subcmd:`avail` or :subcmd:`list` sub-commands,
enclose module names in single quotes if they contain a space character.
* When mentioning the loading, unloading or refreshing evaluation of a module,
report the tags associated to this module as done when printing results of
:subcmd:`list` sub-command.
* Fix :ref:`log-module-command` cookbook recipe not to break Modules
initialization when using provided :file:`siteconfig.tcl` file. (fix issue
#453 with contribution from Eric Burgueño)
* Mention tagging evaluation of a module, when tag list of an already loaded
module is updated.

* Set the :envvar:`__MODULES_AUTOINIT_INPROGRESS` environment variable when
running the :subcmd:`autoinit` sub-command and quit autoinit process if this
variable is found defined and equal to 1 when starting it. Ensure this way
that an autoinit process will not be triggered indefinitely by itself when
the :mconfig:`set_shell_startup` option is enabled and some module loaded at
initialization time relies on the execution of a bash script. (fix issue
#414)
* Remove warning message when unloading a :mfcmd:`prepend-path` or
:mfcmd:`append-path` modulefile command with ``--duplicates`` option set.
(fix issue #421)
* Clarify the module sub-commands that are allowed to be used within a
modulefile. (fix issue #423)
* Install: set in the module magic cookie of the :file:`initrc` configuration
file installed by default the version of Modules required to evaluate this
file.
* Doc: fix documentation of :mfcmd:`getenv` modulefile command to describe
that an empty string is now returned when designated environment variable is
not defined and no default value to return is specified.
Modules 5.0.0 (2021-09-12)
--------------------------
* Remove deprecated :command:`createmodule.sh` and :command:`createmodule.py`
tools as shell script to modulefile conversion is now achieved with the
:subcmd:`sh-to-mod` sub-command.
* Remove mention of the :subcmd:`init*<initadd>` sub-commands in module usage
message to put focus on the collection handling sub-commands.
* Do not declare anymore the ``chdir``, ``module``, ``module-trace``,
``module-verbosity``, ``module-user`` and ``module-log`` commands under the
modulerc Tcl interpreter as no-op commands. A clear error message is
obtained if these commands are still used in modulerc files instead of
silently ignoring them.
* Return by default an empty string rather ``_UNDEFINED_`` on :mfcmd:`getenv`
modulefile command if passed environment variable is not defined.
* Align empty directory name error message obtained on :subcmd:`use`
sub-command with message obtained when module or collection name is empty.
* Accept non-existent modulepath on :subcmd:`use` sub-command.
* Install: installation option :instopt:`--enable-auto-handling` is set on by
default which enables the automated module handling mode (see
:envvar:`MODULES_AUTO_HANDLING`).
* Install: installation option :instopt:`--enable-extended-default` is set on
by default which allows partial module version specification (see
:envvar:`MODULES_EXTENDED_DEFAULT`).
* Install: installation option :instopt:`--enable-advanced-version-spec` is
set on by default which activates the :ref:`Advanced module version
specifiers`
* Install: installation option :instopt:`--enable-color` is set on by default
which enables the ``auto`` output color mode (see :envvar:`MODULES_COLOR`).
* Install: installation option :instopt:`--with-icase` is set to ``search``
by default to activate case insensitive match on search contexts (see
:envvar:`MODULES_ICASE`).
* Install: installation option :instopt:`--enable-new-features` has been reset
following major version change as all the options it implied are now enabled
by default.
* Install: installation option :instopt:`--enable-set-shell-startup` is set
off by default but could be enabled once installed through the
:file:`initrc` configuration file.
* Install: installation option :instopt:`--with-initconf-in` is set to
``etcdir`` by default to locate configuration files in the directory
designated by the :instopt:`--etcdir` option. Therefore the initialization
configuration file is named :file:`initrc` in this directory, and the
modulepath-specific configuration file is named :file:`modulespath`.
* Only look at configuration files found in the location designated by the
:instopt:`--etcdir` or :instopt:`--initdir` option (depending on the value
of :instopt:`--with-initconf-in` option). Configuration files were
previously searched in both locations.
* Install: remove installation option ``--enable-compat-version``.
Compatibility version co-installation is discontinued. :command:`switchml`
shell function and :envvar:`MODULES_USE_COMPAT_VERSION` are thus removed as
well.
* Testsuite: introduce the non-regression quick test mode. When the
:envvar:`QUICKTEST` environment variable is set to ``1``, only the main
tests from the non-regression testsuite are run. When first argument of the
:command:`mt` script is ``quick``, tests are run in quick mode.
* Install: run non-regression testsuite in quick mode in RPM spec file.
* Rename the environment variables that are used by Modules to track loaded
environment state (variables whose name starts with ``MODULES_LM``). A
``__`` prefix is added to the name of these variables to indicate that they
are intended for internal use only.
* Rename the environment variables used to indirectly pass to
:file:`modulecmd.tcl` the value of variables set in quarantine (variables
whose name finishes with ``_modquar``). A
:envvar:`__MODULES_QUAR_<__MODULES_QUAR_\<VAR\>>` prefix is applied to the
name of these variables instead of the ``_modquar`` suffix to indicate they
are intended for Modules internal use of only.
* Update Tcl requirement to version 8.5 as Tcl 8.4 is deprecated since a long
time and this version is not available anymore on recent OS distributions.
Update internal code of :file:`modulecmd.tcl` to take benefit from the
features brought by Tcl 8.5.
* Split source code in several Tcl files hosted in ``tcl`` directory. When
building Modules, the Tcl files are concatenated to make the
:file:`modulecmd.tcl` script.
* Record ``auto-loaded`` tag of loaded modules in :envvar:`__MODULES_LMTAG`
environment variable rather set a specific entry for module in the
``__MODULES_LMNOTUASKED`` environment variable.
* Rename the environment variables used by the reference counting mechanism
of path-like environment variables. A
:envvar:`__MODULES_SHARE_<__MODULES_SHARE_\<VAR\>>` prefix is applied to the
name of these variables instead of the ``_modshare`` suffix to clearly
indicate they are intended for Modules internal use of only.
* Reference counting mechanism is not anymore applied to the Modules-specific
path variables (like :envvar:`LOADEDMODULES`). As a result no
:envvar:`__MODULES_SHARE_\<VAR\>` variable is set in user environment for
these variables. Exception is made for :envvar:`MODULEPATH` environment
variable where the mechanism still applies.
* When an element is added to a path-like variable through the
:mfcmd:`append-path` or :mfcmd:`prepend-path` modulefile commands, add this
element to the associated reference counter variable (named
:envvar:`__MODULES_SHARE_\<VAR\>`) only when this element is added multiple
times to the path-like variable. When an element is removed from a path-like
variable, this element is removed from the reference counter variable when
its counter is equal to 1.
* When the :subcmd:`use` and :subcmd:`unuse` module sub-commands are not
called during a modulefile evaluation, the reference counter associated with
each entry in :envvar:`MODULEPATH` environment variable is ignored. In such
context, a :subcmd:`module use<use>` will not increase the reference counter
of a path entry already defined and a :subcmd:`module unuse<unuse>` will
remove specified path whatever its reference counter value.
* When the :subcmd:`append-path`, :subcmd:`prepend-path` and
:subcmd:`remove-path` module sub-commands are not called during a modulefile
evaluation, the reference counter associated with each entry in targeted
environment variable is ignored. In such context, a
:subcmd:`module append-path/prepend-path<prepend-path>` will not increase
the reference counter of a path entry already defined and a
:subcmd:`module remove-path<remove-path>` will remove specified path
whatever its reference counter value.
* Fix :subcmd:`unuse` sub-command when several modulepaths are specified as a
single argument (i.e., ``/path/to/dir1:/path/to/dir2``). Enabled modulepaths
were not correctly detected when specified this way.
* Doc: clarify that an already defined path is not added again or moved when
passed to the :subcmd:`use` sub-command or the
:mfcmd:`append-path/prepend-path<prepend-path>` modulefile commands. (fix
issue #60)
* Change the :subcmd:`refresh` sub-command to evaluate all loaded modulefiles
and re-apply the non-persistent environment changes they define (i.e., shell
aliases and functions). With this change the :subcmd:`refresh` sub-command
is restored to the behavior it had on Modules version 3.2.
* Evaluate the modulefile commands resulting from a :mfcmd:`source-sh` command
through the current modulefile Tcl interpreter in order to evaluate them
according to the current modulefile evaluation mode.
* When initializing Modules, refresh the loaded modules in case some user
environment is already configured. This is especially useful when starting a
sub-shell session as it ensures that the loaded environment in parent shell
is correctly inherited, as the :subcmd:`refresh` sub-command re-applies the
non-persistent environment configuration (i.e., shell alias and function
that are not exported to the sub-shell). (fix issue #86)
* Init: add example code in default :file:`initrc`, the initialization script
of Modules, to either restore user's default collection if it exists or load
a predefined module list at the end of the initialization process.
* When initializing Modules, evaluate the :file:`initrc` configuration file in
addition to the the :file:`modulespath` configuration file and not instead
of this file. :file:`initrc` is evaluated after :file:`modulespath` file.
* When the installation option :instopt:`--enable-modulespath` is set, the
list of modulepath to enable by default is now only defined in the
:file:`modulespath` configuration file and not anymore in the :file:`initrc`
configuration file.
* No error is raised when evaluating in ``display`` mode a modulefile without
a value specified for the :mfcmd:`variant` it defines. This change helps to
learn all the variant a modulefile defines. As a result, the unspecified
variant is not instantiated in the :mfvar:`ModuleVariant` array variable.
(fix issue #406)
* When running the :mfcmd:`unsetenv` modulefile command on an unload
evaluation, do not unset designated environment variable if no value to
restore is provided.
* Fix :mfcmd:`unsetenv` to distinguish between being called on a unload
evaluation without a value to restore or with an empty string value to
restore.
* Make :mfcmd:`system` modulefile command available from a modulerc evaluation
context whatever the underlying module evaluation mode.
* Make :mfcmd:`is-used` modulefile command available from a modulerc
evaluation context.
* Remove internal state ``tcl_version_lt85`` as Tcl 8.5+ is now a requirement.
* Forbid use of :subcmd:`module source<source>` command in modulefile or in an
initialization rc file, the ``source`` Tcl command should be used instead.
:subcmd:`source` sub-command should only be called from the command-line.
* Report the modules loading and unloading during the :command:`module`
command initialization (i.e., during the evaluation of the :file:`initrc`
configuration file). These report messages are disabled when the
:mconfig:`verbosity` configuration option is set to ``concise`` or
``silent``.
* During a module :subcmd:`restore` or :subcmd:`source`, only report the
module load and unload directly triggered by these sub-commands. Load and
unload triggered by other modules are reported through the automated module
handling messages of the main modules.
* Enforce use of the module magic cookie (i.e., ``#%Module``) at the start of
global or user rc files, :file:`initrc` configuration file or any scriptfile
passed for evaluation to the :subcmd:`source` sub-command. These files are
not evaluated and an error is produced if the magic cookie is missing or if
the optional version number placed after the cookie string is higher than
the version of the :file:`modulecmd.tcl` script in use.
* Doc: alphabetically sort installation option in :ref:`INSTALL` document.
* Update the :instopt:`--enable-quarantine-support` installation option to
control a :mconfig:`quarantine_support` configuration option. When this
option is enabled, the :subcmd:`autoinit` sub-command produces the shell
code for the :command:`module` shell function definition with quarantine
mechanism support. When disabled, code is generated without quarantine
support.
* Install: installation option :instopt:`--enable-quarantine-support` is set
off by default.
* Introduce the :envvar:`MODULES_QUARANTINE_SUPPORT` environment variable to
control the :mconfig:`quarantine_support` configuration option once Modules
is installed. To enable the quarantine mechanism,
:envvar:`MODULES_QUARANTINE_SUPPORT` should be set to ``1`` prior Modules
initialization or :mconfig:`quarantine_support` configuration option should
be set to ``1`` in the :file:`initrc` configuration file.
* Quarantine mechanism code in the Modules shell initialization scripts is now
always defined and mechanism always applies if some environment variables
are defined in :envvar:`MODULES_RUN_QUARANTINE`.
* Code in the :file:`modulecmd.tcl` script to restore environment variables
put in quarantine is now always generated and applies if the
:envvar:`__MODULES_QUARANTINE_SET` environment variable is set to ``1``.
This variable is set by the Modules initialization script prior calling the
:subcmd:`autoinit` sub-command or by the :command:`module` shell function if
it has been generated with quarantine support enabled.
* Install: installation option :instopt:`--enable-silent-shell-debug-support`
is set off by default.
* Code to silence shell debug properties in the Modules shell initialization
scripts is now always defined and mechanism applies if
:envvar:`MODULES_SILENT_SHELL_DEBUG` environment variable is set to ``1``.
* Code to silence shell debug properties in the :command:`module` shell
function could now be enabled if :envvar:`MODULES_SILENT_SHELL_DEBUG` is set
to ``1`` prior Modules initialization or if the
:mconfig:`silent_shell_debug` configuration option is set to ``1`` in the
:file:`initrc` configuration file.
* Doc: clarify TOC and title of :ref:`MIGRATING<MIGRATING>` document.
* Doc: extend description of Modules configuration steps of in :ref:`INSTALL`
document.
* Doc: document :file:`initrc` and :file:`modulespath` configuration files in
:ref:`module(1)` man page.
* Install: replace :file:`example.txt` by :file:`INSTALL.txt` guide in RPM.
* Doc/Install: rename ``diff_v3_v4`` document into :ref:`changes<changes>`.
* Doc: reorganize :ref:`changes` document to let room to describe Modules 5
changes.
.. _4.8 release notes:
Modules 4.8.0 (2021-07-14)
--------------------------
* Introduce the :subcmd:`edit` sub-command that opens modulefile passed as
argument in a text editor. Modulefile can be specified like with any other
sub-command, leveraging defined symbolic versions, aliases or using advanced
version specifiers.
* Add the :mconfig:`editor` configuration option to select the text editor to
use with :subcmd:`edit` sub-command. When this option is set through the
:subcmd:`config` sub-command, the :envvar:`MODULES_EDITOR` environment
variable is set. The :instopt:`--with-editor` installation option controls
the default value of :mconfig:`editor` configuration option. If not set at
installation time, ``vi`` is set as default editor.
* Default value of :mconfig:`editor` configuration option is overridden by the
:envvar:`VISUAL` or the :envvar:`EDITOR` environment variables, which are
both in turn overridden by the :envvar:`MODULES_EDITOR` environment
variable.
* Doc: fix :file:`modulecmd.tcl` internal state check in recipes example
codes. (fix issue #396)
* The :ref:`Advanced module version specifiers` mechanism now allows the use
of version range in version list (for instance ``mod@:1.2,1.4:1.6,1.8:``).
Such specification helps to exclude specific versions. (fix issue #397)
* Install: fix installation scripts to allow building Modules when its
repository is set as a git submodule. (fix issue #398)
* Doc: demonstrate in the :ref:`source-script-in-modulefile` recipe how to use
the :mfcmd:`source-sh` command when software provide a specific
initialization script for each shell it supports. (fix issue #399)
* When defining a shell function with the :mfcmd:`set-function` modulefile
command, only export this function when using the Bash shell (using the
``export -f`` shell command) to make it available in sub-shell contexts.
Shell function export is not supported on other kind of sh shell (sh, ksh
and zsh). (fix issue #401)
* Doc: add :ref:`variants` design notes.
* Add the :mfcmd:`variant` modulefile command that enables to pass down
arguments, specified when designating the module to evaluate, within
modulefile evaluation context. This command defines a variant name and a
list of allowed values. When evaluated, :mfcmd:`variant` instantiates an
element in the :mfvar:`ModuleVariant` array whose name equals variant name
and value is set with value specified for variant when module is designated.
If specified value does not correspond to an allowed value or if no value
is specified for variant an error is raised.
* Enhance the :ref:`Advanced module version specifiers` to handle variant
specification following `Spack`_'s syntax (e.g., *name=value*). When the
:mconfig:`advanced_version_spec` configuration is enabled, variant could be
specified anywhere a module can be specified.
* Add the ``--default`` option to the :mfcmd:`variant` modulefile command to
indicate the default value of the variant to apply when the designation of
the evaluating module does not mention this variant.
* Add the ``--boolean`` option to the :mfcmd:`variant` modulefile command to
indicate that the variant defined is of the Boolean type, thus no list of
accepted value is expected.
* Enhance the :ref:`Advanced module version specifiers` to handle Boolean
variant specification following `Spack`_'s syntax (e.g., *+name*, *~name*
and *-name*). The *-name* syntax is not supported on :ref:`ml(1)` command as
the minus sign already means to unload designated module.
* Accept any minus argument (*-word*) set after the sub-command name when the
:mconfig:`advanced_version_spec` configuration is enabled and if sub-command
accepts :ref:`Advanced module version specifiers` (like :subcmd:`load` or
:subcmd:`unload` sub-commands). A *false* value may be set to Boolean
variant this way.
* Add the :mconfig:`variant_shortcut` configuration option to define shortcut
characters that could be used to specify and report module variants. Default
value for this option could be set at installation time with the
:instopt:`--with-variant-shortcut` option. No variant shortcut is defined by
default. This value could be superseded by setting up the
:mconfig:`variant_shortcut` option with :subcmd:`config` sub-command. Which
sets the :envvar:`MODULES_VARIANT_SHORTCUT` environment variable.
* Enhance the :ref:`Advanced module version specifiers` to handle variant
shortcut specification (e.g., *<shortcut>value*).
* Record in user loaded environment, with
:envvar:`MODULES_LMVARIANT<__MODULES_LMVARIANT>` environment variable, the
value specified for the variants defined in the loaded modulefiles and their
properties (if it is a Boolean variant and if the value set is the default
one).
* Add the ``variant`` element in the allowed value list of the
:mconfig:`list_output` and :mconfig:`list_terse_output` configuration
options. Set this new element in the default value list of the
:mconfig:`list_output` option. When set, the variant defined for loaded
modules are reported on module :subcmd:`list` command output.
* Add the ``va`` color key in default light and dark color palettes to
graphically enhance the report of variant value.
* Update the key section to explain on :subcmd:`list` sub-command output the
reported variant elements (*name=value*, *+name*, *-name* or
*<shortcut>value*)
* Record variant specification of loaded modules when saving collections and
reload specified variants when restoring these collections.
* When :mconfig:`collection_pin_version` configuration is disabled, only
record in collections the variants whose value is not the default one.
* Update module designation in error, warning or informational messages to
report variant specification enclosed in curly braces (*{}*), enclose module
name and version or variant specification in single quotes (*''*) if they
contain a space character and highlight the module designation in report
message if configured.
* Introduce the :mfcmd:`getvariant` modulefile command to query for currently
evaluating module the value of a given variant name.
* When translating the ``@loaded`` version specifier also retrieve the variant
specified for corresponding loaded module.
* Update hide, forbid and tag mechanisms to apply them only if they match
selected module variant.
* Any variant defined in module specification passed as argument to search
sub-commands (:subcmd:`avail`, :subcmd:`whatis`, :subcmd:`is-avail`,
:subcmd:`path` and :subcmd:`paths`) is ignored.
* Raise an error if a variant named ``version`` is declared in a modulefile to
let room for the future implementation of this specific variant.
* Doc: describe in the :ref:`changes` document argument handling change on
:mfcmd:`setenv` since v3.2. (fix issue #402)
* Introduce the :subcmd:`try-load` sub-command which like :subcmd:`load`
sub-command tries to load the modulefile passed as argument, but does not
complain if this modulefile cannot be found. (fix issue #392)
* Init: fix stderr redirection in fish shell initialization script, now that
use of the ``^`` character to redirect stderr is disabled by default (fish
>=3.3).
* Protect quarantine mechanism code from ``rcexpandparam`` Zsh option when
initializing the :command:`module` command on this shell. (fix issue #403)
.. _4.7 release notes:
Modules 4.7.1 (2021-04-06)
--------------------------
* Doc: clarify the license terms used by the project. (fix issue #389)
* Align all files from the Modules project under the GPLv2+ license. Scripts
and libraries that were previously licensed with GPLv3+ have been moved to
GPLv2+ with the consent of their respective copyright holders. (fix issue
#389)
* Revert "Install: have :file:`configure` script assume the ``.`` dot
directory when invoked without the prepended ``./``" as consent was not
obtained from author to re-license the contribution to GPLv2+.
* Doc: fixes few typos in :ref:`module(1)` and :ref:`modulefile(4)`.
* Update the :subcmd:`sh-to-mod` mechanism to support version 3.2 of the fish
shell. Fish 3.2 introduces the ``.`` builtin command that should be
regexp-escaped when determining the shell functions or aliases defined by
the script analyzed by :subcmd:`sh-to-mod`.
* Vim: update addon files to highlight modulefile variables
:mfvar:`ModuleTool`, :mfvar:`ModuleToolVersion` and
:mfvar:`ModulesCurrentModulefile`.
* Doc: update the description and default value of the
:instopt:`--with-dark-background-colors` and
:instopt:`--with-light-background-colors` installation options.
* Doc: add description of changes that occurred on versions 4.6 and 4.7 for
the :instopt:`--with-dark-background-colors` and
:instopt:`--with-light-background-colors` installation options and for the
:envvar:`MODULES_COLORS` environment variable.
* Doc: correct the default value of the :instopt:`--with-tag-abbrev`
installation option.
* Doc: add :ref:`sticky-modules-rcp` cookbook recipe.
Modules 4.7.0 (2021-02-19)
--------------------------
* Doc: simplify TOC of :ref:`MIGRATING` document
* Add the :mfvar:`ModuleTool` and :mfvar:`ModuleToolVersion` Modules
variables to determine during modulefile or modulerc evaluation the name and
version of the *module* implementation currently in use.
* Introduce the :mfcmd:`versioncmp` modulefile command to compare two version
strings passed as argument.
* Enable the use of wildcard character to designate multiple directories at
once in :file:`modulespath` configuration file. (fix issue #125)
* Distinguish aliases from symbolic versions in
:envvar:`MODULES_LMALTNAME<__MODULES_LMALTNAME>` environment variable.
Prefix these alias entries with the ``al|`` string.
* Fetch modulefile modification time only if required by :subcmd:`list`
sub-command display format.
* Use symbolic versions recorded in environment, with
:envvar:`MODULES_LMALTNAME<__MODULES_LMALTNAME>` variable, to report the
symbols applying to loaded modules on :subcmd:`list` sub-command. Modulerc
files are not evaluated anymore when performing a module list.
* Move the definition of the :envvar:`FPATH` environment variable for Modules
initialization on ksh shell from the initialization script of this shell to
the resulting output of the :subcmd:`autoinit` sub-command.
* Introduce the :mconfig:`shells_with_ksh_fpath` configuration option to
define a list of shell where to ensure that any ksh sub-shell will get the
module function defined by use of the :envvar:`FPATH` environment variable.
When the :mconfig:`shells_with_ksh_fpath` option is set through the
:subcmd:`config` sub-command, the :envvar:`MODULES_SHELLS_WITH_KSH_FPATH`
environment variable is set. Accepted values are a list of shell among *sh*,
*bash*, *csh*, *tcsh* and *fish* separated by colon character (``:``).
* Add the :mconfig:`implicit_requirement` configuration option to control
whether a prereq or a conflict requirement should be implicitly set onto
modules respectively specified on :mfcmd:`module load<module>` or
:mfcmd:`module unload<module>` commands in modulefile. Default value for
this option could be set at configure time with the
:instopt:`--enable-implicit-requirement` option (enabled by default). This
value could be superseded by setting up the :mconfig:`implicit_requirement`
option with :subcmd:`config` sub-command. Which sets the
:envvar:`MODULES_IMPLICIT_REQUIREMENT` environment variable. (fix issue
#260)
* Add the ``--not-req`` option to the :mfcmd:`module` modulefile command to
inhibit for its ``load`` and ``unload`` sub-commands the definition of a
prereq or conflict requirement onto specified modules.
* Add the ``lpopState`` and ``currentState`` procedures to respectively remove
or return the last entry from the list of values of a given state.
* Add the ``topState`` and ``depthState`` procedures to respectively return
the first element from or the number of elements in the list of values of a
given state.
* Remove the pre-definition of runtime states with no specific property. These
basic states are defined on-the-fly which implied they are not reported on a
:subcmd:`module config --dump-state<config>` command unless if instantiated.
* Introduce the ``loaded`` symbolic version among advanced version specifiers
(e.g. ``foo@loaded``) to designate the currently loaded version of specified
module. (fix issue #366)
* Doc: add *Module tags* design notes.
* Report tags applying to the modules returned by the :subcmd:`avail`
sub-command. Adapt the regular, terse and JSON output styles to report these
tags along the module they are attached to (enclosed in ``<>``). Reported
tags currently are states that apply to modules: ``auto-loaded``,
``forbidden``, ``hidden``, ``loaded``, ``nearly-forbidden``, ``sticky`` and
``super-sticky``.
* Record tags applying to each loaded module in the
:envvar:`MODULES_LMTAG<__MODULES_LMTAG>` environment variable to make this
information persist after module being loaded.
* Report tags applying to the loaded modules returned by the :subcmd:`list`
sub-command. Adapt the regular and JSON output styles to report these tags
along the module they are attached to (enclosed in ``<>``). Reported tags
currently are states applying to loaded modules: ``auto-loaded``,
``hidden-loaded``, ``nearly-forbidden``, ``sticky`` and ``super-sticky``.
* Introduce the :mfcmd:`module-info tags<module-info>` modulefile command to
query the tags that apply to the currently evaluated modulefile.
* Add the :mfcmd:`module-tag` modulefile command to associate tag to
designated modulefile. Those tags are reported on :subcmd:`avail` and
:subcmd:`list` sub-commands along the module they are attached to.
:mfcmd:`module-tag` supports the advanced module version specifier syntax.
* Add the :mconfig:`tag_abbrev` configuration option to define abbreviated
strings for module tags and use these abbreviations instead of tag names
when reporting tags on :subcmd:`avail` and :subcmd:`list` command results.
Default value for this option could be set at configure time with the
:instopt:`--with-tag-abbrev` option. By default the following abbreviations
are set: ``aL`` for *auto-loaded*, ``F`` for *forbidden*, ``H`` for
*hidden*, ``H`` for *hidden-loaded*, ``L`` for *loaded*, ``nF`` for
*nearly-forbidden*, ``S`` for *sticky*, ``sS`` for *super-sticky*. This
value could be superseded by setting up the :mconfig:`tag_abbrev` option
with :subcmd:`config` sub-command. Which sets the
:envvar:`MODULES_TAG_ABBREV` environment variable.
* A Select Graphic Rendition (SGR) code can be associated to module tag names
or abbreviation strings in the color palette to graphically render these
tags over the module name they are associated to. The default light and dark
color palettes have been updated to set a color code for all basic module
tags. When a color code is set for a tag, it is then graphically rendered
over the module names and not reported along module name by its tag name or
abbreviation. When multiple colored tags apply to a given module, each tag
is graphically rendered over a sub-part of the module name.
* Add the :mconfig:`tag_color_name` configuration option to designate module
tags whose graphical rendering should be applied to their own name or
abbreviation rather than over the module name they are attached to.
Default value for this option could be set at configure time with the
:instopt:`--with-tag-color-name` option (empty by default). This value could
be superseded by setting up the :mconfig:`tag_color_name` option with
:subcmd:`config` sub-command. Which sets the
:envvar:`MODULES_TAG_COLOR_NAME` environment variable.
* Add the ``--hidden-loaded`` option to the :mfcmd:`module-hide` modulefile
command that indicates module should be hidden once loaded. When set, the
``hidden-loaded`` module tag applies to module specification set on
:mfcmd:`module-hide` command.
* Do not report on :subcmd:`list` sub-command results the loaded modules
associated with the ``hidden-loaded`` tag, unless if the :option:`--all`
option is set.
* Doc: add an ``hidden-loaded`` example in the *Hide and forbid modules*
cookbook recipe.
* Introduce the ``verbose2`` verbosity level between ``verbose`` and ``trace``
levels. Verbose2 mode can be enabled by setting the :mconfig:`verbosity`
config to the ``verbose2`` value or by using the :option:`-v` command-line
switch twice.
* Do not report the load, unload or switch of modules set ``hidden-loaded`` if
these modules have been loaded, unloaded or switched automatically. Unless
the verbosity mode is set to ``verbose2`` or any higher level or if any
specific messages have to be reported for these module evaluations.
* Report when trying to load a module which is already loaded or when trying
to unload a module which is not loaded in case the verbosity mode is set to
``verbose2`` or any higher level. (fix issue #187)
* Doc: improve readability of version 4 improvements in :ref:`changes`
document.
* Introduce stickiness: module tagged ``sticky`` with :mfcmd:`module-tag`
command cannot be unloaded unless if the unload is forced or if the module
is reloaded. (fix issue #269)
* Introduce super-stickiness: module tagged ``super-sticky`` with
:mfcmd:`module-tag` command cannot be unloaded even if the unload is forced
unless if the module is reloaded. (fix issue #269)
* Allow swap of sticky or super-sticky modules by another modulefile version
if stickiness definition applies to module parent name. E.g., *foo/1.0* can
be swapped by *foo/2.0* if sticky tag applies to *foo*.
* When forcing purge with a :subcmd:`purge --force<purge>` sub-command, also
unload the modules that are depended by non-unloadable modules.
* Doc: improve readability of Modules installation configuration in
:ref:`INSTALL` document and enable hypertext reference to these elements.
* Doc: improve readability of module command configuration option in
:ref:`module(1)` document and enable hypertext reference to these elements.
* Doc: describe in HTML documentation when installation options, module
command configuration options and options of modulefile command or module
sub-command were introduced.
* Doc: update HTML documentation Table Of Content.
* Doc: improve markup of module sub-commands, modulefile commands,
installation option, module configuration option across documentation.
* Doc: colorize terminal output examples in :ref:`MIGRATING` document.
* Abort modulefile read if first file content chunk does not start with the
``#%Module`` magic cookie. (fix issue #375)
* Install: add installation option :instopt:`--enable-new-features` that
enables all at once the installation options that are disabled by default
due to the substantial behavior changes they imply.
* Add a *Key* section at the end of :subcmd:`avail` and :subcmd:`list`
sub-commands to explain the meaning of graphical renditions or of elements
set in parentheses or chevrons along module name.
* Fix output of :subcmd:`avail` and :subcmd:`list` sub-commands on very small
terminal width. (fix issue #378)
* Add :mconfig:`mcookie_version_check` configuration to define if version set
in modulefile magic cookie should be checked against :command:`module`
current version to determine if modulefile can be evaluated. The new
configuration, which is enabled by default, can be set at installation time
with configure option :instopt:`--enable-mcookie-version-check` or can be
superseded later on with the :envvar:`MODULES_MCOOKIE_VERSION_CHECK`
environment variable. (fix issue #377)
* Fix output of modulefile evaluation error stack trace on very small terminal
width. (fix issues #379 and #381)
* Correct :subcmd:`config` sub-command to set :mconfig:`nearly_forbidden_days`
configuration. (fix issue #380)
* Init: reduce usage of helper variables in :file:`bash_completion` and
:file:`tcsh_completion` that are showing up in the output of the shell's
``set`` command. (fix issue #382 with contribution from Colin Marquardt)
* Consider modulepath starting with a reference to an environment variable as
absolute. (fix issue #376)
* Consider the :subcmd:`module load<load>` performed in the user or the global
RC file like load commands issued from initialization RC file. (fix issue
#372)
* Install: have :file:`configure` script assume the ``.`` dot directory when
invoked without the prepended ``./``. (contribution from R.K. Owen)
* Install: disable the Makefile rules to build the HTML documentation in case
if the documentation is found pre-built in the dist archive.
* Install: do not flag documentation as pre-built if :file:`configure` script
is ran another time after building docs.
* Restrict the value accepted by :mconfig:`nearly_forbidden_days`
configuration and :instopt:`--with-nearly-forbidden-days` installation
option to integers comprised between 0 and 365.
* Install: color *ERROR* and *WARNING* message headers produced by
:file:`configure` script if output is sent to a terminal.
* Install: split error messages produced by :file:`configure` script over an
additional line when too long.
* Doc: add *Output configuration* design notes.
* Introduce the :mconfig:`avail_output` and :mconfig:`avail_terse_output`
configuration options to define the content to report in addition to the
available module names respectively for :subcmd:`avail` sub-command regular
and terse output modes. Excepted value for these configuration options is a
colon separated list of elements to report. Default value is
``modulepath:alias:dirwsym:sym:tag:key`` for :mconfig:`avail_output` and
``modulepath:alias:dirwsym:sym:tag`` for :mconfig:`avail_terse_output`.
These values can be changed at installation time respectively with the
:instopt:`--with-avail-output` and :instopt:`--with-avail-terse-output`
options. These values can then be superseded by using the :subcmd:`config`
sub-command which sets the :envvar:`MODULES_AVAIL_OUTPUT` and
:envvar:`MODULES_AVAIL_TERSE_OUTPUT` environment variables.
* Introduce the :mconfig:`list_output` and :mconfig:`list_terse_output`
configuration options to define the content to report in addition to the
available module names respectively for :subcmd:`list` sub-command regular
and terse output modes. Excepted value for these configuration options is a
colon separated list of elements to report. Default value is
``header:idx:sym:tag:key`` for :mconfig:`list_output` and ``header`` for
:mconfig:`list_terse_output`. These values can be changed at installation
time respectively with the :instopt:`--with-list-output` and
:instopt:`--with-list-terse-output` options. These values can then be
superseded by using the :subcmd:`config` sub-command which sets the
:envvar:`MODULES_LIST_OUTPUT` and :envvar:`MODULES_LIST_TERSE_OUTPUT`
environment variables.
* Add the :option:`--output`/:option:`-o` command-line switches to supersede
the output configuration of :subcmd:`avail` or :subcmd:`list` sub-commands
on their regular or terse output modes.
* Remove the ``avail_report_dir_sym`` and ``avail_report_mfile_sym`` locked
configuration options whose behaviors can now be obtained by respectively
adding the ``dirwsym`` and ``sym`` elements to the :mconfig:`avail_output`
or :mconfig:`avail_terse_output` configuration options.
* When ``modulepath`` is omitted from the content to report on :subcmd:`avail`
sub-command, available modules collected from global/user rc and enabled
modulepaths are aggregated and reported all together.
* Install: print generated file names rather commands executed to generate
these files on Makefile build targets. Output obtained when building Modules
is this way simplified. When option ``V=1`` is passed to ``make``, the
verbose mode is enabled and run commands are shown. The simplified ``make``
output does not apply to the install, test and clean targets or any target
similar to them.
* Install: fix configure and build files of Modules Tcl extension library to
make them compatible with autoconf >=2.69.
* Script: correctly detect previous Modules version number released from a
side git branch on :command:`mpub` command.
* Install: align RPM spec file syntax with spec file used on Fedora. Add
missing build dependency on ``make`` package. Also remove obsolete ``Group``
RPM tag.
* Add the :mconfig:`term_width` configuration option to set the width of the
output. This configuration option is set to ``0`` by default, which means
that the output width is the full terminal width. The
:option:`--width`/:option:`-w` command line switches are added to supersede
the value of the configuration option. (fix issue #359 with contribution
from Anaïs Gaertner)
* Doc: add a *Get Modules* section in :ref:`INSTALL` document to provide
download links for Modules' sources. (fix issue #387)
.. _4.6 release notes:
Modules 4.6.1 (2020-11-14)
--------------------------
* Lib: implement ``initStateClockSeconds`` as a Tcl command in
libtclenvmodules to provide an optimized way to retrieve current Epoch time.
* Lib: implement ``parseDateTimeArg`` as a Tcl command in libtclenvmodules to
provide an optimized way to convert a datetime string into an Epoch time.
* When full module specification is equal to ``@``, raise an error as no
module name is provided. (fix issue #362)
* Optimize internal recording of hidden module and tag specification when
parsing modulerc files in order to reduce the time taken to test if a given
module is hidden or if a given tag applies to it.
* Script: add the ability to select the benchmark test to perform on
:command:`mb` utility.
* Doc: add *Use new features without breaking old module command* cookbook
recipe
* Doc: rework option description for :mfcmd:`module-hide` and
:mfcmd:`module-forbid` commands in :ref:`modulefile(4)` document.
* Doc: describe in :ref:`changes` document that shell special characters like
backticks are escaped when used in values starting Modules 4.0. (fix issue
#365)
* Doc: make the ENVIRONMENT section from :ref:`modulefile(4)` man page point
to the ENVIRONMENT section of :ref:`module(1)` man page.
* Fix :subcmd:`clear` sub-command to unset the
:envvar:`MODULES_LMSOURCESH<__MODULES_LMSOURCESH>` environment variable.
(fix issue #367)
* Correctly return on :subcmd:`avail` sub-command a symbolic version defined
in a global RC file when specifically searched. (fix issue #368)
* Fix module hiding resolution for symbolic versions defined in a global RC
file when :mfcmd:`module-hide` statements are set in the modulepath where
the modulefiles targeted by these symbols are located. (fix issue #369)
* When a module fails to unload during a :subcmd:`purge` sub-command, preserve
loaded the modules it requires to keep environment consistent. (fix issue
#370)
* Doc: add *Hide and forbid modules* cookbook recipe.
Modules 4.6.0 (2020-09-16)
--------------------------
* Rework internal state handling to gather all state definitions in a global
array and use the same initialization and retrieval procedure, named
``getState``, for all these states.
* Add the ``setState``, ``unsetState``, ``lappendState``, ``isStateDefined``
and ``isStateEqual`` procedures to provide unified ways to set or check the
value of state.
* Introduce the :subcmd:`sh-to-mod` sub-command, to evaluate shell script and
determine the environment changes it does. Corresponding modulefile
content is outputted as a result. Changes on environment variables, shell
aliases, shell functions and current working directory are tracked. The
following shells are supported: sh, dash, csh, tcsh, bash, ksh, ksh93, zsh
and fish.
* Doc: add *Source shell script in modulefile* design notes.
* Introduce the :mfcmd:`source-sh` modulefile command, to evaluate shell
script and apply resulting environment changes through modulefile commands.
When a modulefile using :mfcmd:`source-sh` modulefile command is loaded, the
modulefile commands resulting from shell script evaluation are recorded in
the :envvar:`MODULES_LMSOURCESH<__MODULES_LMSOURCESH>` environment variable
to be able to undo these environment changes when modulefile is unloaded and
to report the modulefile commands used when modulefile is displayed. The
same kind of environment changes than the :subcmd:`sh-to-mod` sub-command
are tracked. The same list of shells than :subcmd:`sh-to-mod` sub-command
are supported. (fix issue #346)
* Doc: add *Source shell script in modulefile* cookbook recipe.
* Doc: embed new Modules logo on website, online README and documentation
portal.
* Install: disable by default the build of Modules compatibility version. From
now on, option :instopt:`--enable-compat-version` has to be set to trigger
this build.
* Introduce the ``username`` sub-command to the :mfcmd:`module-info`
modulefile command to get the username of the user currently running
:file:`modulecmd.tcl` or to test a string passed as argument corresponds to
this username.
* Introduce the ``usergroups`` sub-command to the :mfcmd:`module-info`
modulefile command to get all the groups of the user currently running
:file:`modulecmd.tcl` or to test a string passed as argument corresponds to
one of these groups.
* Doc: improve markup of :ref:`NEWS` and :ref:`MIGRATING` documents starting
from this 4.6 version to enable references to module sub-commands, command
line switches, environment variables and modulefile Tcl commands.
* Use inclusive terminology to eliminate *master* and *slave* terms as much as
possible from code source and documentation.
* Doc: use a versioned magic cookie in examples that demonstrate new
modulefile features. (fix issue #349)
* Introduce the :instopt:`--enable-multilib-support` configure option to add
mechanism in :file:`modulecmd.tcl` to look at an alternative location to
find the Modules Tcl extension library in case this library cannot be found
at its main location.
* Lib: remove *fetch_hidden* argument from ``getFilesInDirectory`` procedure
of Modules Tcl extension library.
* Doc: add *Hide or forbid modulefile* design notes.
* Add the :mfcmd:`module-hide` modulefile command, to dynamically hide
modulefile, module alias or symbolic version matching passed specification.
When hidden, a modulefile, an alias or a symbolic version is not reported
nor selected unless referred by its exact name, like for module whose name
or version starts with a dot character. :mfcmd:`module-hide` supports the
advanced module version specifiers. (fix issue #202)
* Add option ``--soft`` to the :mfcmd:`module-hide` modulefile command to
introduce a soften level of camouflage: modules targeted by such hide
directive are made visible as soon as their root name is part of search
query.
* Add option ``--hard`` to the :mfcmd:`module-hide` modulefile command to
introduce a hardened level of camouflage: modules targeted by such hide
directive keep being hidden even if they are fully matched by search query.
* Do not report among :subcmd:`whatis` search result the modulefiles with
version name prefixed by a dot character and targeted by a symbolic version
unless if they are precisely searched.
* When a loading module has hidden alternative names (hidden due to their
name or version starting with a dot character or because they match a
:mfcmd:`module-hide` statement), these alternative names are not recorded in
environment unless if they are not hard-hidden and if they have been used in
query to select loading module.
* On :subcmd:`avail` sub-command, remove hidden symbolic versions from the
list to display along modulefile or directory they target, unless these
symbols are not hard-hidden and are used in query to search modules.
* When the :option:`--default` filter of :subcmd:`avail` sub-command is set,
unhide all the *default* symbolic versions or modules targeted by these
symbols unless if they are hard-hidden.
* Define the *default* and *latest* automatic symbolic versions only if
relative module name matches search query to ensure all elements for this
module have been processed prior assigning the symbols.
* In case a symbolic version is transitively applied toward a modulefile, like
for instance when this symbol is first set onto a directory, record the
resolution of each transitively applied symbol. By doing so, a module
:subcmd:`load` tentative using the transitively applied symbolic version
will now correctly resolve to the modulefile targeted by symbol.
* Fix use of the advanced version specifiers in arguments to the
:mfcmd:`is-avail` modulefile command.
* Introduce the :option:`--all`/:option:`-a` option for :subcmd:`avail`,
:subcmd:`aliases`, :subcmd:`whatis` and :subcmd:`search` sub-commands, to
include in the search process all hidden modulefiles, module aliases or
symbolic versions. Hard-hidden modules stay hidden even if
:option:`--all`/:option:`-a` option is used.
* Add the :mfcmd:`module-forbid` modulefile command, to dynamically forbid
evaluation of modulefile matching passed specification. When forbidden, a
module cannot be loaded and an access error is obtained when trying to
evaluate them. :mfcmd:`module-forbid` supports the advanced module version
specifiers.
* Add ``--not-user`` and ``--not-group`` options to :mfcmd:`module-hide` and
:mfcmd:`module-forbid` modulefile commands to ignore hiding or forbidding
definition if current user is respectively part of specified username list
or member of one of specified group list.
* Add ``--before`` and ``--after`` options to :mfcmd:`module-hide` and
:mfcmd:`module-forbid` modulefile commands to ignore hiding or forbidding
definition respectively after and before a specified date time. Accepted
date time format is ``YYYY-MM-DD[THH:MM]``.
* Add ``--message`` option to :mfcmd:`module-forbid` modulefile command to
supplement the error message obtained when trying to evaluate a forbidden
module.
* When a module that will soon be forbidden (as the date limit specified on
the ``--after`` option of a matching :mfcmd:`module-forbid` command is near)
is evaluated, warn user this module access will soon be denied.
* The range of time the above warning appears can be controlled with the
:mconfig:`nearly_forbidden_days` configuration option, whose value equals to
the number of days prior the module starts to be forbidden. This
configuration is set to ``14`` (days) by default and this value can be
controlled at :file:`configure` time with
:instopt:`--with-nearly-forbidden-days` option. When the
:mconfig:`nearly_forbidden_days` configuration is set through the
:subcmd:`config` sub-command, the :envvar:`MODULES_NEARLY_FORBIDDEN_DAYS`
environment variable is set.
* Add ``--nearly-message`` option to :mfcmd:`module-forbid` modulefile command
to supplement the warning message obtained when evaluating a nearly
forbidden module.
* Add the ``debug2`` verbosity level, to report each call of
:file:`modulecmd.tcl` internal procedures in addition to debug messages.
Debug2 mode can be enabled by setting the :mconfig:`verbosity` config to the
``debug2`` value or by using the :option:`-D` command-line switch twice.
* Install: look for ``make`` rather ``gmake`` on MinGW and build library with
a ``.dll`` extension on this platform.
* Add the ``trace`` verbosity level, to report details on module searches,
resolutions, selections and evaluations. Trace mode can be enabled by
setting the ``verbosity`` config to the ``trace`` value or by using the
:option:`-T`/:option:`--trace` command-line switches.
* Introduce the ``tr`` key in the color palette to specifically render trace
messages. Default value for ``tr`` key is ``2`` (decreased intensity).
* When trying to set an environment variable to an empty value on the Windows
platform, unset this environment variable instead to cope with the
underlying OS behavior.
.. _4.5 release notes:
Modules 4.5.3 (2020-08-31)
--------------------------
* Install: take into account the ``--build``, ``--host``, ``--target``,
``--enable-dependency-tracking`` and ``--disable-dependency-tracking``
configure options to transmit them to the :file:`configure` scripts of
Modules Tcl extension library and Modules compatibility version. (fix issue
#354)
* Install: ignore some regular options of an Autoconf :file:`configure` script
that are useless for this project but usually implied in build macros (like
RPM ``%configure`` macro).
* Install: ignore unsupported ``--enable-*`` and ``--with-*`` options on
:file:`configure` script rather raise an error and add support to define
environment variable and build system type as :file:`configure` script
arguments to comply with `GNU configuration recommendations`_.
* Install: fix :file:`modulecmd` pre-alternatives check in RPM spec file.
* Install: use ``%make_build`` and ``%make_install`` macros in RPM spec file.
* When :mfcmd:`module switch<module>` command is used in modulefile, do not
state when processing it a conflict over switched-off module if its
specification on the ``module switch`` command also matches switched-on
module's specification. Allow this way the replacement of any loaded version
of a module for a specific one required by currently loading module. (fix
issue #355)
* Correctly report failed attempts to load module requirements expressed with
advanced version specifiers. (fix issue #356)
.. _GNU configuration recommendations: https://www.gnu.org/prep/standards/html_node/Configuration.html
Modules 4.5.2 (2020-07-30)
--------------------------
* Init: :subcmd:`list` and :subcmd:`source` sub-commands do not take available
modules as argument in fish completion script.
* Init: fix option list for :subcmd:`search` sub-command in bash completion
script.
* Fix double error counter increase when modulefile evaluation breaks.
* Install: adapt :file:`configure` script to pass to the :file:`configure`
script of Modules compatibility version only a subset of the options it
supports (most commonly used options).
* Install: raise an error when an unknown option is passed to
:file:`configure` script rather silently ignore it. (fix issue #348)
* Install: enable the definition of installation directory options of
:file:`configure` script with the ``--option value`` syntax in addition to
the ``--option=value`` syntax. (fix issue #348)
* Doc: alphabetically sort sub-commands of :mfcmd:`module-info` modulefile Tcl
command in :ref:`modulefile(4)` document.
* Script: clean previously built environment-modules RPMs in :command:`mrel`.
* Clearly separate quarantine variable definition from tclsh binary on
:file:`modulecmd.tcl` evaluated command call in ``_module_raw`` function for
*sh*, *bash*, *ksh* and *zsh* shells. (fix issue #350)
* Doc: clarify in documentation index that Environment Modules should not be
confused with language-specific modules. (contribution from Rob Hurt)
* Adapt conflict detection tests to ensure a module loaded by its full
pathname will not detect itself as a conflict when declaring a reflexive
conflict. (fix issue #352)
* Adapt the :command:`mrel` and :command:`mpub` commands to produce new
Modules release from a *vZ.Y.x* git branch rather than from the repository
main branch.
Modules 4.5.1 (2020-06-01)
--------------------------
* Install: consistently output Makefile warning messages on stderr.
* Script: add the ``mrel`` script, that automates build of the Modules release
files and performs tests over these distribution files to guaranty their
correctness.
* Script: add the ``mpub`` script, that automates Modules new release
publishing over git repositories and websites.
* Install: remove project-specific tools from git repository export thus from
release distribution files.
* Disable pager when ``clear`` sub-command is called from ``ml`` shortcut
command. (fix issue #338)
* In case a modulefile evaluation fails, environment context prior this failed
evaluation is restored. Fix environment variable restoration mechanism to
keep the link that monitors and updates environment variable array ``env``
in every Tcl sub-interpreters. (fix issue #340)
* Ensure environment variable change at the Tcl interpreter level is
propagated to every sub-interpreters used to evaluate modulefiles or
modulercs. (fix issue #342)
* Use absolute path to load Modules Tcl extension library. (fix issue #344
with contribution from Roy Storey)
* Fix formatting of error stack trace not to look for internal commands to
withdraw if start-up stack pattern cannot be matched.
Modules 4.5.0 (2020-04-07)
--------------------------
* Doc: fix typos and grammar mistakes on :ref:`module(1)`,
:ref:`modulefile(4)` and :ref:`changes` documents. (contribution from Colin
Marquardt)
* Doc: update cookbook recipes to highlight code of the Tcl scripts included.
(contribution from Colin Marquardt)
* Doc: improve markup of :ref:`module(1)`, :ref:`modulefile(4)` and
:ref:`changes` documents to enable references to module sub-commands,
command line switches, environment variables and modulefile Tcl commands.
(contribution from Colin Marquardt)
* Doc: alphabetically sort module sub-commands, command-line switches,
environment variables and modulefile Tcl commands in :ref:`module(1)` and
:ref:`modulefile(4)` documents.
* Introduce the ``ml`` command, a handy frontend to the ``module`` command.
``ml`` reduces the number of characters to type to trigger ``module``. With
no argument ``ml`` is equivalent to ``module list``, ``ml mod`` corresponds
to ``module load mod`` and ``ml -mod`` means ``module unload mod``. Multiple
modules to either load or unload can be combined on a single command. ``ml``
accepts all command-line switches and sub-commands accepted by ``module``
command. ``ml`` command is defined by default. Its definition can be
controlled at ``./configure`` time with :instopt:`--enable-ml` option or
later on with :mconfig:`ml` configuration option (which defines
``MODULES_ML`` environment variable when set).
* Fix module sub-command abbreviation match to ensure passed abbreviated
form fully match sub-command, not only its minimal abbreviated form. As an
example, ``lod`` or ``loda`` do not match anymore the ``load``
sub-command, ``lo`` or ``loa`` still do.
* Add the ``-j``/``--json`` command line switches to the ``avail``, ``list``,
``savelist``, ``whatis`` and ``search`` module sub-commands to render their
output in `JSON`_ format. (fix issue #303)
* Script: remove need to build project management-specific tools
(``mtreview``, ``mb``, ``mlprof`` and ``playdemo``) prior using them.
* Script: gather all distributed and maintained scripts in a ``script``
directory at the root of the project repository tree.
* Install: provide Windows-specific batch files when ``./configure`` option
:instopt:`--enable-windows-support` is set. module command wrapper
``module.cmd`` is installed in ``bindir`` and initialization script
``cmd.cmd`` in ``initdir``. Those batch files are relocatable and expect
``modulecmd.tcl`` in ``..\libexec`` directory. (fix issue #272 with
contribution from Jacques Raphanel)
* Install: add ml command wrapper ``ml.cmd`` and install it in ``bindir`` when
``./configure`` option :instopt:`--enable-windows-support` is set.
* Install: introduce envml command wrapper ``envml.cmd`` for Windows ``cmd``
shell and install it in ``bindir`` when ``./configure`` option
:instopt:`--enable-windows-support` is set. (contribution from Jacques
Raphanel)
* Doc: improve documentation portal index.
* Install: add ``dist-win`` target to Makefile in order to build a
distribution zipball containing the required files to run Modules on a
Windows platform. ``INSTALL.bat`` and ``UNINSTALL.bat`` Windows batch files
are introduced and shipped in the zipball to automate installation and basic
configuration of Modules on the Windows platform.
* Doc: update :ref:`INSTALL-win` document to describe how to install Modules
with newly provided Windows-specific distribution zipball.
* Install: enable build of Modules from ``git archive`` tarball or zipball
exports (like download source archives automatically provided on GitHub
project)
* Install: ship reStructuredText and MarkDown source documents at the root of
Modules distribution tarball rather their built txt counterpart.
* Script: fix ``createmodule.sh`` script to correctly analyses environment
when shell functions are found defined in it.
* Script: inhibit output generated by scripts evaluated by ``createmodule.sh``
and ``createmodule.py`` to ensure these outputs will not get in the way when
analyzing the environment changes. (fix issue #309)
* Correctly handle symbolic version target including a whitespace in their
name.
* Testsuite: output test error details whatever the testsuite run verbose
mode.
* Install: adapt configure script and Makefile to detect ``python`` command
location and set it as shebang for ``createmodule.py`` and
``gitlog2changelog.py``. If ``python`` command is not found, ``python3``
then ``python2`` are searched.
* Install: enable to pass a specific Python interpreter command name or
location at configure step with :instopt:`--with-python` option. Specified
command name or location should be found on build system only if building
from git repository.
* Install: build ``createmodule.py`` script and install it in ``bindir``.
* Install: update RPM spec file to explicitly define Python interpreter
location.
* Script: fix ``createmodule.py`` script for Python3 (fix issue #315 with
contribution from Armin Wehrfritz)
* Lift Perl variable strictness when defining ``_mlstatus`` variable in case
``modulecmd.tcl`` output is directly evaluated without use of the ``module``
sub-routine in Perl script. (with contribution from Andrey Maslennikov)
* Script: fix path de-duplication in ``createmodule.sh``. (fix issue #316)
* Doc: add *Handling Compiler and other Package Dependencies* cookbook
recipe, which discusses various strategies for creating modulefiles for
packages with multiple builds depending on previously loaded compiler,
MPI libraries, etc. (contribution from Tom Payerle)
* Init: test availability of ``compopt`` Bash builtin prior using it in
Bash completion script to avoid error with versions of this shell older
than 4.0. (fix issue #318)
* Install: adapt configure step to detect if ``sed`` option ``-E`` is
supported and fallback to ``-r`` otherwise in shell completion scripts.
(fix issue #317)
* Add support for the ``NO_COLOR`` environment variable
(https://no-color.org/) which when set (regardless of its value) prevents
the addition of ANSI color. When set, ``NO_COLOR`` prevails over
``CLICOLOR`` and ``CLICOLOR_FORCE`` environment variables. ``MODULES_COLOR``
overrides these three variables. (fix issue #310)
* Script: when analyzing environment variable changes in ``createmodule.sh``
applied by shell script passed as argument, produce a ``setenv`` modulefile
statement for any variable found set prior script evaluation and for which
value is completely changed after script evaluation. (fix issue #320)
* When an error message is composed of multiple lines, render it in the same
way whether it is part of a block message or not: lines after the first one
are prepended with a 2-space padding. As a result error messages appear
clearly separated from each other.
* Append to the error message the error stack trace when a general unknown
error occurs in ``modulecmd.tcl`` and provide a link to encourage users to
report such error to the GitHub project.
* Add to the error message the error stack trace for errors occurring during
site-specific configuration evaluation. Error stack is expunged from the
``modulecmd.tcl`` internals to only report information relevant to
site-specific configuration file.
* When an error occurs during the evaluation of a modulefile or a modulerc,
report associated error stack trace expunged from ``modulecmd.tcl`` internal
references to only output useful information for users.
* GitHub: add issue templates to guide people submitting a bug report or a
feature request.
* Doc: provide a link toward issues that have been fixed between versions 3.2
and 4.0 in :ref:`changes` document.
* Script: introduce ``envml.cmd`` script for Windows platform providing
similar behavior than ``envml`` Bash script. (contribution from Jacques
Raphanel)
* Init: add Bash shell completion for the ``ml`` command. (contribution from
Adrien Cotte)
* Fix Fish shell stderr redirection for newer Fish versions. (fix issue #325)
* Correctly handle modulefiles and modulepaths containing a space character in
their name whether they are used from the command-line, in collections,
within modulefiles or from loaded environment definitions.
* Doc: add *Default and latest version specifiers* design note.
* An ``avail`` search over a symbolic version targeting a directory now
correctly returns the special modules (alias and virtual module) lying in
this directory. (fix issue #327)
* ``whatis`` and ``paths`` searches only return special modules (symbolic
version, alias and virtual modules) that fully match search query, not
those that partially match it. (fix issue #328)
* alias and virtual module whose name mention a directory that does not
exists are correctly handled. (fix issue #168)
* Hide special modules (aliases, symbolic versions and virtual modules)
whose version name starts with a dot character (``.``) from ``avail``,
``whatis`` and ``paths`` searches if their query does not fully match
special module name. (fix issue #329)
* Filter-out from the output of the ``aliases`` sub-command all hidden
aliases, symbolic versions or hidden modules targeted by a non-hidden
symbolic version. (fix issue #330)
* Enable resolution of default module in module sub-directory when this
default symbol targets a hidden directory (whose name starts with a dot
character). (fix issue #331)
* Doc: clarify hidden module location in :ref:`modulefile(4)` man page.
* Install: define ``LD_PRELOAD`` as quarantine var along with
``LD_LIBRARY_PATH`` in RPM specfile.
* When :mconfig:`implicit_default` and :mconfig:`advanced_version_spec`
configuration are enabled, automatically define a ``default`` and ``latest``
symbolic version for each module name (at each module depth for deep
modules) if those version names does not already exist. (fix issue #210)
* Once a module is loaded, the automatically defined symbols associated to it
are recorded in loaded environment in the ``MODULES_LMALTNAME`` environment
variable. They are distinguished from the other alternative names applying
to the module by a ``as|`` prefix, which qualifies their *auto symbol* type.
* When an advanced version specifier list contains symbolic version
references, fix resolving to honor default version if part of the specified
list. (fix issue #334)

.. _4.4 release notes:
Modules 4.4.1 (2020-01-03)
--------------------------
* Fix error and warning messages relative to dependency management to enclose
dependency specification in single quotes to clearly distinguish
specification from each other.
* Skip output of module loading message if module is already loaded.
* Doc: add demonstration material played at SC19 to promote the new features
of Modules.
* Contrib: add ``playdemo`` script to play recorded demonstration cast.
* Doc: add a web anchor to each modulefile Tcl command, module sub-command
and module environment variable documentation.
* Install: update RPM spec file to enable build on ``el8``.
* Doc: fix RST syntax for bullet lists in design docs. (fix issue #306)
* In case ``module avail`` query does not match a directory but only its
contained elements (for instance ``module av mod/7`` matches ``mod/7.1`` and
``mod/7.2`` but not ``mod/``), fix query processing to correctly return
latest or default element in case ``--latest`` or ``--default`` flags are
set.
* In case a ``module avail`` query performed in a no-indepth mode with
``--latest`` or ``--default`` flags either enabled or disabled, fix query
processing to return directory elements if they are part of result.
* When a ``module avail`` query performed in no-indepth mode targets a virtual
module, fix result to filter-out the directory holding the virtual module
from result.
* Fix ``module avail --default`` queries when modulefile default version does
not match query: select latest version from modulefiles matching query
unless ``implicit_default`` configuration is disabled in which case no
default version is returned.
* Improve highlighting of module ``avail`` and ``whatis`` search result by
coloring module names matching search query expressed with the advanced
version specifiers. ``name@1,3`` or ``name@1:3`` queries now highlight
``name/1`` and ``name/3`` strings found in search result.
* Contrib: add the ``mlprof`` script which wraps ``modulecmd.tcl`` to collect
profiling information on its execution.
* Contrib: adapt ``mb`` script to profile ``modulecmd.tcl`` run tests rather
bench them when ``profile`` argument is passed to the script.
* Improve overall performances of module names and versions comparison by
introducing optimized procedures and caching in memory module search
results.
Modules 4.4.0 (2019-11-17)
--------------------------
* Doc: add *Return file basename on module-info name for full path modulefile*
recipe to cookbook. (fix issue #297)
* Rework internal handling of configuration options to gather all option
definitions in a global array and use the same initialization and retrieval
procedure, named ``getConf``, for all these options.
* Add the ``setConf``, ``unsetConf`` and ``lappendConf`` procedures to provide
unified ways to set the value of configuration option. These procedures
should be used in site configuration files to override configuration option
value instead of directly setting corresponding option variable as it was
done in previous Modules releases.
* Add the ability to match module specification in a case insensitive manner.
Default case sensitiveness behavior is set at ``./configure`` time with the
``--with-icase`` option. It could be superseded with the ``MODULES_ICASE``
environment variable, that could be set with ``config`` module sub-command
through the ``icase`` option. Command-line switch ``--icase`` (``-i``)
enables to supersede defined case sensitiveness configuration. (fix issue
#212 with contribution from Eric Deveaud)
* Introduce the extended default mechanism, to help selecting a module when
only the first numbers in its version are specified. Starting portion of the
version, part separated from the rest of the version string by a ``.``
character, will get matched to the appropriate complete version name. In
case multiple versions match partial version specified and only one module
should be returned, default version (implicit or explicit) among matches is
returned. In case ``implicit_default`` option is disabled and no explicit
default is found among matches, an error is returned. This mechanism is
enabled through a new configuration option named ``extended_default`` (which
defines ``MODULES_EXTENDED_DEFAULT`` environment variable when set). It may
be enabled by default in ``modulecmd.tcl`` script with option
``--enable-extended-default`` passed to the ``./configure`` script.
* Introduce the advanced module version specifiers mechanism to specify finer
constraints on module version. This new feature enables to filter the module
selection to a given version list or range by specifying after the module
name a version constraint prefixed by the ``@`` character. It leverages the
version specifier syntax of the `Spack`_ package manager. A single version
can be specified with the ``@version`` syntax, a list of versions with
``@version1,version2,...``, a greater than or equal to range with
``@version1:`` syntax, a less than or equal to range with ``@:version2`` and
an in between or equal to range with ``@version1:version2`` syntax. In case
``implicit_default`` option is disabled and no explicit default is found
among version specifier matches, an error is returned. This mechanism is
enabled through a new configuration option named ``advanced_version_spec``
(which defines ``MODULES_ADVANCED_VERSION_SPEC`` environment variable when
set). It may be enabled by default in ``modulecmd.tcl`` script with option
``--enable-advanced-version-spec`` passed to the ``./configure`` script.
* Conflict defined with a generic module name or an advanced version specifier
may match multiple loaded modules (generally in case multiple loaded modules
share same root name). Loaded environment analysis has been fixed to bind
conflict to all loaded modules matching it. As a result the *Dependent
Reload* mechanism is not triggered when one loaded module matching conflict
is removed if another loaded module still match the conflict.
* Doc: add *Module selection contexts*, *Insensitive case*, *Extended default*
and *Advanced module version specifiers* design notes.
* Make ``MODULESHOME`` environment variable controllable through the
``config`` sub-command with ``home`` configuration option. A
``--with-moduleshome`` argument is also added to the ./configure script to
set specific default value for this option at installation time. (fix issue
#292)
.. _Spack: https://github.com/spack/spack
.. _4.3 release notes:
Modules 4.3.1 (2019-09-21)
--------------------------
* Contrib: add ``mb`` script to bench Modules versions.
* Correct ``modulecmd.tcl`` script startup to correctly report error in case
Tcl extension library fails to load. (fix issue #284)
* Install: fix typo on ``CFLAGS`` definition in ``lib/Makefile``. (fix issue
#287 with contribution from Felix Neumärker)
* Remove useless code in Modules Tcl extension library
* Make URLs in README correctly rendered in HTML. (contribution from Per
Persson)
* Doc: clarify modulefile evaluation modes in modulefile.4 man page. (fix
issue #289)
* When looking at the closest match among loaded modules when switching module
with just a single module argument specified, load the information on the
currently set environment to get the alternative names of loaded modules
prior to look at closest module match. (fix issue #290)
* Doc: describe the way to determine the site-specific configuration script
location in cookbook recipes implying the installation of such a file. (fix
issue #266)
* Doc: add *Log module command* recipe to cookbook. (fix issue #283)
* Doc: add *Expose procedures and variables to modulefiles* recipe to
cookbook.
* Doc: add *Make defined modulepaths persist over sudo* recipe to cookbook.
* Doc: add *Ensure user fully qualify the modules they use* recipe to
cookbook.
* Introduce the ``wa_277`` configuration option to workaround an issue with
Tcsh history mechanism. Default ``module`` alias definition for Tcsh hits
an issue with shell history mechanism: erroneous history entries are
recorded each time the ``module`` command is called. When ``wa_277`` option
is enabled (which sets the ``MODULES_WA_277`` environment variable to *1*),
an alternative module alias is defined which fixes the history mechanism
issue. However the alternative definition of the module alias weakens shell
evaluation of the code produced by modulefiles. Characters with special
meaning for Tcsh shell (like *{* and *}*) may not be used anymore in shell
alias definition elsewhere the evaluation of the code produced by
modulefiles will return a syntax error. (fix issue #277)
* Doc: add *Tips for Code Reuse in Modulefiles* recipe to cookbook.
(contribution from Tom Payerle)
* Fix the ``whatis`` and ``paths`` sub-command results for module symbolic
versions targeting a directory when ``implicit_default`` configuration
option is disabled. No error is returned and same result is now obtained
whether the symbolic name or its target is used as argument for those two
sub-commands. (fix issue #294)
* Fix the ``whatis`` and ``paths`` sub-command results for module aliases
targeting a directory when ``implicit_default`` configuration option is
disabled. No error is returned and same result is now obtained whether the
alias name or its target is used as argument for those two sub-commands.
(fix issue #295)
* Rework all the ternary operator expressions in ``modulecmd.tcl`` that may
result in a *nan* value (whatever the case used to write this string) as the
``expr`` Tcl command raises an error when it returns such a value, which
breaks Modules as soon as a modulefile, an alias or a symbolic version is
named *nan*. (fix issue #296)
Modules 4.3.0 (2019-07-26)
--------------------------
* Introduce Vim addon files to highlight the modulefile syntax. Installation
of these files, which is enabled by default, is controlled by the
``--enable-vim-addons`` and ``--vimdatadir`` configure options.
(contribution from Felix Neumärker)
* If modulefile is fully read, cache the content read and the file header
computed to avoid another file read if the same modulefile need to be read
multiple times.
* Except for path, paths, list, avail and aliases module commands always fully
read a modulefile whether its full content is needed or just its header to
verify its validity. Proceed this way to only read file once on commands
that first just check modulefile validity then read again valid files to get
their full content.
* Introduce Modules Tcl extension library (written in C) to extend Tcl
language in order to provide more optimized I/O commands to read a file or a
directory content than native Tcl commands do.
* Install: add ``--libdir``, ``--enable-libtclenvmodules``, ``--with-tcl`` and
``--with-tclinclude`` options to configure script to control
libtclenvmodules build and installation.
* When an error is caught during modulecmd.tcl first initialization steps,
ensure the error report facility is initialized to render error message.
* When looking for modulefiles in enabled modulepaths, take ``.modulerc`` file
found at the root of a modulepath directory into account. Which means these
rc files are now evaluated like global rc files and can be used to define
module aliases targeting modulefiles stored in the underlying file tree.
* Correctly get available default (-d) and latest (-L) version whether search
pattern is passed with an ending forward slash character or not or if it
contains a ``*`` wildcard character.
* Append a forward slash character to any directory result of an avail command
to better distinguish these directories from regular files.
* Introduce the ability to control whether ``avail`` command search results
should recursively include or not modulefiles from directories matching
search query by use of the ``--indepth`` and ``--no-indepth`` command-line
switches or the environment variable ``MODULES_AVAIL_INDEPTH``. Default
behavior is set at the ``./configure`` time with the
``--enable-avail-indepth`` and ``--disable-avail-indepth`` switches. (fix
issue #150)
* Update ``bash``, ``fish`` and ``zsh`` completion scripts to propose
available modulefiles in the no in depth mode.
* Add the ability to graphically enhance some part of the produced output to
improve readability by the use of the ``--color`` command-line switch or the
``MODULES_COLOR`` environment variable. Both accept the following values:
``never``, ``auto`` and ``always``. When color mode is set to ``auto``,
output is colored if stderr is attached to a terminal. Default color mode
could be controlled at configure time with the ``--enable-color`` and the
``--disable-color`` option, which respectively correspond to the ``auto``
and ``never`` color mode.
* Control the color to apply to each element with the ``MODULES_COLORS``
environment variable or the ``--with-dark-background-colors`` and
``--with-light-background-colors`` configure options. These variable and
options take as value a colon-separated list in the same fashion
``LS_COLORS`` does. In this list, each element that should be highlighted is
associated to a Select Graphic Rendition (SGR) code.
* Inform Modules of the terminal background color with the
``MODULES_TERM_BACKGROUND`` environment variable or the
``--with-terminal-background`` configure option, which helps to determine if
either the dark or light background colors should be used to color output in
case no specific color set is defined with the ``MODULES_COLORS``.
* Color prefix tag of debug, error, warning, module error and info messages.
* Highlight the modulefile or collection name when reporting messages for a
an action made over this modulefile or collection.
* Color the modulepaths reported on a ``use`` command.
* Highlight title of separator lines or column name of table header.
* Color modulepaths, directories, aliases and symbols reported by the
``avail``, ``aliases``, ``list``, ``whatis`` and ``search`` commands.
* When color mode is enabled and module aliases are colored, do not associate
them a ``@`` tag as the color already distinguish them from regular
modulefile.
* When color mode is enabled and a Select Graphic Rendition (SGR) code is set
for the ``default`` modulefile symbol, apply this SGR code to the modulefile
name instead of associating it the ``default`` symbol tag.
* Highlight matched module search query string among ``avail``, ``whatis`` and
``search`` command results.
* Highlight the modulefile and collection full path name on ``display``,
``help``, ``test`` and ``saveshow`` command reports.
* Color modulefile Tcl commands set in a modulefile on a ``display`` command
report.
* Color module commands set in a collection on a ``saveshow`` command report.
* Re-introduce ``clear`` sub-command. (fix issue #203)
* Leverage ``--force`` command-line switch on ``clear`` sub-command to skip
confirmation dialog. (fix issue #268)
* Init: improve readability of variable definition operations by writing one
definition operation per line rather having multiple commands on a single
line like ``VAR=val; export VAR``. (fix issue #225)
* Add the ability to define a site-specific configuration file with an
environment variable: ``MODULES_SITECONFIG``. When set, the script file
pointed by the variable is sourced (if readable) after the site-specific
configuration file initially defined in ``modulecmd.tcl``. (contribution
from Ben Bowers, fix issue #234)
* Doc: add description in the module.1 man page of ``MODULERCFILE`` in the
environment section and ``siteconfig.tcl`` in the files section.
* Install: provide at installation time a bare site-specific configuration
script in designated ``etcdir`` if no pre-existing ``siteconfig.tcl`` file
is found at designated location.
* Introduce the ``config`` sub-command to get and set ``modulecmd.tcl``
options and to report its current state.
* Contrib: update ``createmodule.py`` script to support execution from the
*cmd* shell. (contribution from Jacques Raphanel, fix issue #270)
* Add the ability to configure when unloading a module and multiple loaded
modules match request if firstly loaded module should be chosen or lastly
loaded module. Configure option ``--with-unload-match-order`` defines this
setting which can be superseded with the ``MODULES_UNLOAD_MATCH_ORDER``
environment variable. This variable can be set with the option
``unload_match_order`` on the ``config`` sub-command. By default, lastly
loaded module is selected. It is recommended to keep this behavior when the
modulefiles used express dependencies between each other.
* Add the ability to configure whether an implicit default version should be
defined for modules with no default version explicitly defined. When
enabled, which stays the default behavior, a module version is automatically
selected (latest one) when the generic name of the module is passed. When
implicit default selection is disabled, the name of modules to evaluate
should be fully qualified elsewhere an error is returned. This option is set
at ``./configure`` time with the ``--enable-implicit-default`` and
``--disable-implicit-default`` options. It could be superseded with the
``MODULES_IMPLICIT_DEFAULT`` environment variable, that could be set with
``config`` module sub-command through the ``implicit_default`` option.
* Install: add to the configure script the ``--with-locked-configs`` option to
ignore environment variable superseding of Modules configurations defined in
``modulecmd.tcl`` script. Lockable configuration option are
``extra_siteconfig`` and ``implicit_default``. Currently locked options are
reported through the ``locked_configs`` option on the ``config``
sub-command.
* Introduce the ability to control the module search match. Search query
string should match module name start or any part of module fully qualified
name. Default search match behavior is set at ``./configure`` time with the
``--with-search-match`` option. It could be superseded with the
``MODULES_SEARCH_MATCH`` environment variable, that could be set with
``config`` module sub-command through the ``search_match`` option.
Command-line switches ``--starts-with`` (``-S``) and ``--contains`` (``-C``)
for ``avail`` module sub-command enable to supersede defined search match
configuration.
* Introduce the ability not to set the shell startup file that ensure
``module`` command is defined once shell has been initialized. Setting shell
startup file currently means defining ``ENV`` and ``BASH_ENV`` environment
variables to the Modules bourne shell initialization script. ``./configure``
options ``--enable-set-shell-startup`` and ``--disable-set-shell-startup``
define if shell startup should be set or not by default. It could be
superseded with the ``MODULES_SET_SHELL_STARTUP`` environment variable, that
could be set with ``config`` module sub-command through the
``set_shell_startup`` option.
* Cookbook: add the *test-modulefiles* recipe. (fix issue #182 with
contribution from Colin Marquardt)
* Fix location of global RC file to ``@etcdir@/rc`` instead of
``@prefix@/etc/rc`` to cope with ``@etcdir@`` specific setup (``@etcdir@``
defaults to ``@prefix@/etc``).
* Take into account Modules initialization configurations found in ``etc``
directory if they exist rather in ``init`` directory. If ``initrc``
configuration file is found in ``etcdir`` then it is preferred over
``modulerc`` file in ``initdir``. Following the same trend, ``modulespath``
configuration file is found in ``etcdir`` then it is preferred over
``.modulespath`` file in ``initdir``.
* Introduce the ability to install the Modules initialization configuration
files in the ``etcdir`` rather than in the ``initdir``. A new configure
option is introduced for this task: ``--with-initconf-in``. Accepted values
for this option are: ``etcdir`` or ``initdir`` (default).
* Add the ``--enable-modulespath`` configure option, which is an alias for the
``--enable-dotmodulespath`` option as ``.modulespath`` configuration file is
named ``modulespath`` when installed in ``etcdic``.
* Install: update RPM spec file to disable ``set_shell_startup`` option by
default, set ``/etc/environment-modules`` as configuration directory and
store Modules initialization configuration files in it.
* Report an error when a module load or unload evaluation aborts due to the
use of the ``break`` or ``exit`` modulefile commands. This error
notification clarifies that module evaluation failed. (fix issue #267)
* Remove the message block display output for the ``reload``, ``purge`` and
``restore`` sub-commands to preserve this output style for modulefile
evaluation modes (load, unload and switch) and thus clarify understanding.
* When unloading a module that contains a ``module load`` or ``module switch``
modulefile command, inhibit the unload performed of the useless requirement
when auto_handling mode is disabled if currently performing a ``purge``,
``reload`` or ``restore`` sub-command. As the unload sequence is determined
and managed from these top commands.
* Add ability to control module command message verbosity with configuration
option. Introduced verbosity levels from the least to the most verbose are
``silent``, ``concise``, ``normal``, ``verbose`` and ``debug``. This option
could be set at ``./configure`` time with ``--with-verbosity`` option.
It could be superseded with the ``MODULES_VERBOSITY`` environment variable,
that could be set with ``config`` module sub-command through the
``verbosity`` option. Silent, verbose and debug verbosity modes can be set
at the command-line level respectively with ``--silent``/``-s``,
``--verbose``/``-v`` and ``--debug``/``-D`` command-line switches. (fix
issue #204)
* When verbosity level is ``normal`` or higher, reports every module loads or
unloads performed to ``restore`` a collection or ``source`` a scriptfile,
even if there is no specific message to output for these module evaluations.
Clarifies what module evaluations have been triggered by these sub-commands.
* Also honor the ``CLICOLOR`` and ``CLICOLOR_FORCE`` environment variables to
define color mode. (fix issue #279)
.. _4.2 release notes:
Modules 4.2.5 (2019-07-08)
--------------------------
* Correctly escape ``?`` character in shell alias. (fix issue #275)
* When resolving the enabled list of modulepaths, ensure resolved path
entries are unique. (fix issue #274)
* Right trim '#' characters from the fetched modulefile magic cookie string
to ensure a correct compatibility version comparison. Useful when modulefile
first line is equal to ``#%Module4.2##############``.
* Fix argument parsing for the ``append-path``, ``prepend-path`` and
``remove-path`` modulefile commands to consider every arguments found after
the variable name as variable values and not command option even if argument
starts with ``-`` character. (fix issue #278)
* Fix automatic loading of modulefiles when multiple module names are set on a
single ``module load`` modulefile command. When auto_handling mode was
disabled, the load of not loaded modules was not achieved as soon as some
modules on this list were already loaded. (fix issue #281)
Modules 4.2.4 (2019-04-26)
--------------------------
* Better track each module evaluation and the context associated to it in
order to report a more accurate information on the additional modules
loaded or unloaded when proceeding the main evaluation request. (fix issue
#244, #245, #246, #247 and #248)
* Doc: preserve quotes and dashes when making HTML docs. (fix issue #250 with
contribution from Riccardo Coccioli)
* Fix hanging ``list`` sub-command when terminal width is equal to the single
column text width to be printed. (contribution from Jesper Dahlberg)
* During an additional evaluation triggered by an automated module handling
mechanism, ensure warning and error messages are reported under the message
block of the main evaluation. (fix issue #252)
* During the unload of a module when the automated module handling mode is
disabled, report a warning message for each unload of a useless requirement
that fails as done when the automated module handling mode is enabled. (fix
issue #253)
* When multiple modules are listed on a ``prereq`` command, drop the output of
those modules that fails to load (by the *Requirement Load* automated
mechanism) to only keep the output of the module whose load succeed. (fix
issue #254)
* Fix ``switch`` sub-command when the switched-off module cannot be unloaded
when other loaded modules depend on it. Whole switch process is failed and
no load of the switched-on module is attempted. (fix issue #251)
* When switching modules, report failure of switched-off module unload or
switched-on module load under the message block of the switch action. A
failed switched-off module unload is reported as an error, as it aborts the
switch evaluation, whereas a failed switched-on module load is reported as a
warning. (fix issue #255)
* When a module requirement is seen missing but the load of this module was
attempted, report a more specific error or warning message to let user
understand that the load of the requirement was attempted but failed. (fix
issue #257)
* When loading a module, report any missing requirement on the message
reporting block corresponding to this module load. This warning or error
message comes in addition to the eventual *Requirement Load* message
reported under the message block of the main evaluation. (fix issue #258)
* When unloading a module which has some dependent module still loaded,
produce a more specific error or warning message if an evaluation of these
dependent modules has been realized or if the unload of the required module
is forced. (fix issue #259)
* When a conflicting module is seen loaded but the unload of this module was
attempted, report a *Conflict Unload* error or warning message toward the
main evaluation message block. (fix issue #261)
* When loading a module, report any loaded conflict on the message reporting
block corresponding to this module load. This warning or error message comes
in addition to the eventual *Conflict Unload* message reported under the
message block of the main evaluation. (fix issue #261)
* Correctly report loading state of conflicting module. (fix issue #262)
* Adapt warning, error and info messages relative to the *Dependent Reload*
mechanism to distinguish the unload phase from the load (reload) phase of
this mechanism. In the automated module handling summary report, unloaded
modules via this mechanism are reported in the *Unloading dependent* list
and modules reloaded afterward are reported against the *Reloading
dependent* list. (fix issue #263)
* When the automated module handling mode is disabled, do not attempt to load
a requirement expressed in a modulefile with a ``module load`` command, if
this requirement is already loaded or loading.
* Skip load or unload evaluation of a module whose respectively load or unload
was already attempted but failed. If this second evaluation attempt occurs
within the same main evaluation frame. (fix issue #264)
* When reloading modules through the *Dependent Reload* automated mechanism,
prevent modules to automatically load of other modules with the ``module
load`` modulefile command, as it is done for the ``prereq`` command. (fix
issue #265)
* Raise an error when an invalid option is set on ``append-path``,
``prepend-path`` or ``remove-path`` modulefile command. (fix issue #249)
* Zsh initializes by default the ``MANPATH`` environment variable to an empty
value when it starts. To preserve ``manpath`` system configuration even
after addition to this variable by modulefiles, set ``MANPATH`` variable to
``:`` if found empty. (improve fix for issue #224)
* Doc: provide a short installation guideline in README file. (fix issue #230)
Modules 4.2.3 (2019-03-23)
--------------------------
* Add all the module dependency-related internal information to those saved
prior a modulefile evaluation in order to correctly restore internal state
in case modulefile evaluation fails.
* Init: in shell initialization scripts, initialize ``MANPATH`` if not set
with a value that preserves ``manpath`` system configuration even after
addition of paths to this variable by modulefiles. (fix issue#224)
* Enable to define an entire path entry to the ``MODULEPATH`` variable which
corresponds to a variable reference only. (fix issue#223)
* Cookbook: add the *modulefiles-in-git* recipe. (contribution from Scott
Johnson)
* When ``module switch`` commands are found in modulefiles, track switched-off
modulefile as a conflict and switched-to modulefile as a requirement to
apply same behaviors than for ``module load`` and ``module unload`` commands
in modulefiles. If ``module switch`` has only one argument, do not define a
conflict toward switched-off modulefile. *CAUTION: it is not recommended to
use module switch command in modulefiles*. (fix issue#229)
* When unloading a module, revert ``module switch`` commands found in
modulefile: switched-on module is converted to a ``module unload``, like for
``module load`` command. Nothing is done for switched-off module, like for
``module unload`` command. (fix issue#226)
* For default element in a modulefile directory which is a module alias that
points to a modulefile, when this modulefile is loaded, it receives as
alternative names the eventual module aliases set on the distant directory
holding the alias pointing to it. (fix issue#231)
* When unloading a module that contains ``module load`` or ``module switch``
commands in its modulefile, select for unload the automatically loaded
requirement module which has been loaded prior its dependent. (fix
issue#232)
* Doc: describe Emacs settings useful for adhering to coding conventions in
CONTRIBUTING guide. (fix issue #233 with contribution from Ben Bowers)
* When looking for a loaded or loading dependency requirement, select among
the eventual multiple candidates the closest match to the dependent module.
* During the unload of a module, if the unload of one of its dependent (by the
*Dependent Unload* mechanism) fails, abort the whole unload process.
Exception made if the force mode is enabled. In this case failing module
stays loaded and the *Dependent Unload* mechanism continues with next module
to unload.
* During the unload of a module, if the unload of one of its useless
requirements (by the *Useless Requirement Unload* mechanism) fails, keep the
requirements of this failing module loaded. Such error is reported as a
warning and it does not stop the whole unload process. (fix issue#240)
* During the load or the unload of a module, if the unload of one of its
dependent (by the *Dependent Reload* mechanism) fails, abort the whole
unload or load process. Exception made if the force mode is enabled. In this
case failing module stays loaded and *Dependent Reload* mechanism continues
with next module to unload. This failing module is removed from the
*Dependent Reload* list, so it will not take part of the load phrase of the
mechanism. (fix issue#239)
* During the load or the unload of a module, if the load of one of its
dependent (by the *Dependent Reload* mechanism) fails, abort the whole
unload or load process. Exception made if the force mode is enabled. In this
case failing module stays loaded and *Dependent Reload* mechanism continues
with next module to load. When the mechanism is applied during a ``switch``
command, force mode is enabled by default on the load phase. (fix issue#241)
* When reloading all loaded modules with the ``reload`` sub-command, if one
reloading module fails to unload or load, abort the whole reload process to
preserve environment sanity. (fix issue#237)
* During the unload of a module when the automated module handling mode is
disabled and this module declares its requirements with the ``module load``
modulefile command. If the unload of one of its useless requirements (by the
*Useless Requirement Unload* mechanism) fails, whole unload process is not
aborted and continue with next module to unload. (fix issue#238)
* Contrib: add ``mtreview`` utility script that analyzes test suite log file
to compare actual and expected output of failed test. ``mt`` does not output
the full test suite logs anymore but only the information produced by
``mtreview`` on failed tests.
* Install: exclude Continuous Integration configurations from dist tarballs.
Modules 4.2.2 (2019-02-17)
--------------------------
* Correct the *Dependent Unload* mechanism when it triggers the unload of 2
modules making together a requirement from another module. This module is
now also added to the dependent modules to unload.
* Doc: add a cookbook section in the documentation and port there the 3
pre-existing recipes: *inhibit-report-info*, *top-priority-values* and
*unload-firstly-loaded*.
* Doc: add a CONTRIBUTING guide.
* Doc: fix a typo on the Python initialization example in module man page.
* Doc: add a FAQ entry to describe the use of module from Makefile. (with
contribution from Robert McLay)
* Trim any white-space, newline or ``;`` characters at the beginning or end of
the function body passed to set-function modulefile command.
* Init: add recognition of the ``--auto``, ``--no-auto`` and ``--force``
command-line switches in fish shell completion script.
* Init: add recognition of the ``--auto``, ``--no-auto``, ``--force``,
``--paginate`` and ``--no-pager`` command-line switches in zsh shell
completion script.
* When the load of a modulefile is asked but a conflict is registered against
this modulefile by an already loaded module, the load evaluation is now
performed and the conflict is checked after this evaluation. If the conflict
is still there, this evaluation (and the evaluation of its requirements) is
rolled back. (fix issue#216)
* Init: fix ``_module_not_yet_loaded`` alias in tcsh completion script to
handle situation when ``noclobber`` variable is set. Also ensure actual
``rm`` command is called and not an alias. (fix issue#219)
* Fix warning message when the load of a modulefile is forced over a reflexive
conflict (message was reported twice).
* When looking at the dependency of a loaded module, only consider requirement
loaded before dependent module (holding a prior position in the loaded
module list) as valid. Those loaded after dependent module are considered as
an unmet dependency thus they are not taking part in the *Dependent Unload*,
the *Useless Requirement Unload* and the *Dependent Reload* mechanisms.
Modules 4.2.1 (2018-11-11)
--------------------------
* Cookbook: add the *inhibit-report-info* recipe.
* Cookbook: port *unload-firstly-loaded* and *top-priority-values* recipes to
v4.2.
* Init: fix listing of loaded modules for *fish* and *tcsh* shell completions.
* Init: fix saved collection listing when no collection found for *bash*,
*zsh*, *tcsh* and *fish* shell completions.
* Adapt ``system`` modulefile Tcl command to execute the command passed as
argument through shell, like it is performed on compatibility version. (fix
issue#205)
* Correctly filter modulefile search memory cache entries when using a full
search result to search later on a specific modulefile.
* Prefix debug messages by information on the current modulefile or modulerc
interpreter if any.
* Init: fix listing of loaded modules on unload and switch sub-commands for
*bash* shell completion.
* Refrain ``module unload`` modulefile command from unloading a module
required by another loading module.
* Enable ``is-loaded`` modulefile Tcl command in modulerc interpretation
context, like done on compatibility version. (fix issue#207)
* Check a required module is not already loading before attempting to load it.
Helps to handle cyclic dependencies.
* Compute loaded modules requirement dependency relations without cycle and
consider the module closing the cycle in a constraint violation state to
avoid reloading loops on the *Dependent Reload* mechanism.
* Safely unset dependency reference when computing dependency relations as
some dependencies expressed may target same module.
* Ensure a loaded module matching multiple entries of a same *or* ``prereq``
will just be considered as one module matching this requirement.
* Init: quote prompt in *csh* and *tcsh* script with ``:q`` rather double
quotes to accommodate prompts with embedded newlines. (fix issue#209 with
contribution from Satya Mishra)
* Init: skip shell environment alteration if ``autoinit`` command fails. (fix
issue#208)
* Reword path-like variable element counter reference handling to simply
ignore the counter values not coherent with the content of related
path-like variable. (fix issue#206)
Modules 4.2.0 (2018-10-18)
--------------------------
* Add ``chdir`` and ``puts`` environment settings to the per-modulefile
evaluation saved context. So previous values of these settings are restored
in case of evaluation failure.
* Fix save and restore of ``x-resource`` environment settings on the
per-modulefile evaluation context.
* Use the correct warning procedure to report the full reference counter
inconsistency message (so this message is fully inhibited during global
``whatis`` evaluations).
* Make ``append-path``, ``prepend-path``, ``remove-path`` and ``unsetenv``
commands alter ``env`` Tcl global array during ``display``, ``help``,
``test`` or ``whatis`` evaluation modes. Thus an invalid argument passed to
these commands will now raise error on these modes. (see
:ref:`v42-variable-change-through-modulefile-evaluation` section in
MIGRATING document)
* On ``whatis`` mode, ``append-path``, ``prepend-path``, ``remove-path``,
``setenv`` and ``unsetenv`` commands initialize variables if undefined but
do not set them to their accurate value for performance concern.
* Clear value instead of unsetting it during an unload mode evaluation of
``setenv`` or ``*-path`` commands to avoid breaking later reference to the
variable in modulefile.
* Make ``getenv`` command returns value on ``help``, ``test`` or ``whatis``
evaluation modes. (fix issue#188)
* Add an argument to the ``getenv`` command to return the value of this
argument if the queried variable is undefined.
* Use a different modulefile interpreter for each evaluation mode.
* Adapt the procedure called for each modulefile command depending on the
evaluation mode to adapt behavior of these commands to the module command
currently running.
* Report calling name and arguments for modulefile commands on ``display``
mode. For the commands evaluated during this mode, trigger this report at
the end of the evaluation.
* Inhibit ``chdir``, ``conflict``, ``module``, ``module-log``,
``module-trace``, ``module-user``, ``module-verbosity``, ``prereq``,
``set-alias``, ``system``, ``unset-alias``, ``x-resource`` commands on
``help``, ``test`` and ``whatis`` evaluation modes.
* Ignore ``chdir``, ``module``, ``module-trace``, ``module-verbosity``,
``module-user`` and ``module-log`` commands found during modulerc
evaluation.
* Correctly restore an empty string value on sub-interpreter global variables
when sanitizing this interpreter between two modulefile/modulerc
evaluations.
* Cache in memory results of a modulefile search to reuse it in case of rerun
instead of re-walking the filesystem.
* Evaluate global rc files once module sub-command is known and registered,
so it can be queried during their evaluation.
* Rename ``_moduleraw`` shell function in ``_module_raw`` to use a common
``_module_`` prefix for all module-related internal shell functions.
* Install: add ``--enable-append-binpath`` and ``--enable-append-manpath``
configure options to append rather prepend the bin or man directory when
adding them to the relative environment variable.
* Doc: clarify documentation for module usage on scripting language like Perl
or Python to mention that arguments to the ``module`` function should be
passed as list and not as a single string.
* When interpreting a ``setenv`` modulefile order during an unload evaluation,
variable is still set to be unset in generated shell code but it is set to
the value defined on the ``setenv`` order in the interpreter context instead
of being cleared.
* Register the conflicts defined by loaded modules in the environment
(variable ``MODULES_LMCONFLICT``) and ensure they keep satisfied. (see
:ref:`v42-conflict-constraints-consistency` section in MIGRATING document)
* Register the prereqs defined by loaded modules in the environment (variable
``MODULES_LMPREREQ``) and ensure they keep satisfied. (see
:ref:`v42-prereq-constraints-consistency` section in MIGRATING document)
* Introduce the automated module handling mode, which consists in additional
actions triggered when loading or unloading a modulefile to satisfy the
dependency constraints it declares. Those actions are when loading a
modulefile: the *Requirement Load* and the *Dependent Reload*. When
unloading a modulefile, *Dependent Unload*, *Useless Requirement Unload* and
*Dependent Reload* actions are triggered. (see
:ref:`v42-automated-module-handling-mode` section in MIGRATING document)
* Track the loaded modules that have been automatically loaded (with
environment variable ``MODULES_LMNOTUASKED``) to distinguish them from
modules that have been explicitly asked by user. This information helps to
determine what module becomes a useless requirement once all its dependent
modules are unloaded.
* Track in saved collections the loaded modules that have been automatically
loaded by add of a ``--notuasked`` argument to ``module load`` collection
lines. So this information is restored in loaded environment when collection
is restored. This ``--notuasked`` argument is ignored outside of a
collection restore context.
* Consider modules loaded from a ``module source`` file as explicitly asked by
user.
* Install: add ``--enable-auto-handling`` configure option to enable or
disable the automatic modulefile handling mechanism.
* Process list of loaded modules or modules to load one by one during the
``restore``, ``purge`` and ``reload`` sub-commands whatever the auto
handling mode is.
* Add the ability to control whether the auto_handling mode should be enabled
or disabled with an environment variable called ``MODULES_AUTO_HANDLING`` or
from the command-line with ``--auto`` and ``--no-auto`` switches. These
command-line switches are ignored when called from modulefile.
* Init: add pager-related command-line options in shell completion scripts.
* Doc: describe ``MODULES_LMCONFLICT``, ``MODULES_LMPREREQ`` and
``MODULES_LMNOTUASKED`` in module.1 man page.
* Add ``-f`` and ``--force`` command-line switches to by-pass dependency
consistency during ``load``, ``unload`` or ``switch`` sub-commands. (see
:ref:`v42-by-passing-module-constraints` section in MIGRATING document)
* Disallow collection ``save`` or loaded modules ``reload`` if some loaded
modules have some of their dependency constraints unsatisfied.
* The *Dependent Reload* action of a ``load``, ``unload`` and ``switch``
sub-commands excludes modules that have unsatisfied constraints and includes
modules whose constraints are satisfied again (when sub-command process
solves a conflict for instance).
* Doc: describe ``--force``, ``--auto`` and ``--no-auto`` command-line
switches and ``MODULES_AUTO_HANDLING`` variable in module.1 man page.
* Ignore directories ``.SYNC`` (DesignSync) and ``.sos`` (SOS) when walking
through modulepath directory content. (contribution from Colin Marquardt)
* Install: look for ``make`` rather ``gmake`` on MSYS2.
* Fix ``exec()`` usage in Python module function definition to retrieve the
correct return status on Python3.
* Cookbook: add the *top-priority-values* and *unload-firstly-loaded* recipes.
* Install: add ``gcc`` to the build requirements in RPM specfile.
* Silent any prereq violation warning message when processing *Dependent
Reload* mechanism or ``purge`` sub-command.
* Doc: mention ``createmodule.sh`` and ``createmodule.py`` scripts in FAQ.
(fix issue#189)
* Register all alternative names of loaded modules in environment with
``MODULES_LMALTNAME`` variable. These names correspond to the symbolic
versions and aliases resolving to the loaded modules. Helps to consistently
solve ``conflict`` or ``prereq`` constraints set over these alternative
names. (fix issue#143 / see
:ref:`v42-consistency-module-load-unload-commands` section in MIGRATING
document)
* Doc: describe ``MODULES_LMALTNAME`` in module.1 man page.
* Install: add ``--with-bin-search-path`` configure option to get in control
of the path list used to search the tools required to build and configure
Modules. (fix issue#164)
* Install: add ``--enable-silent-shell-debug-support`` configure option to add
the ability to control whether or not code to support silent shell debug
should be added to the module function and sh-kind initialization scripts.
(fix issue#166)
* Install: add ``--enable-quarantine-support`` configure option to add the
ability to control whether or not code to support quarantine mechanism
should be added to the module function and initialization scripts.
(fix issue#167)
* Check version set in modulefile magic cookie. If modulefile sets a version
number greater than ``modulecmd.tcl`` script version, this modulefile is not
evaluated like when no magic cookie is set at all. (fix issue#171 / see
:ref:`v42-versioned-magic-cookie` section in MIGRATING document)
* Fix uninitialized variable in procedure producing list of element output.
(fix issue#195)
* Ensure the consistency of ``module load`` modulefile command once the
modulefile defining it has been loaded by assimilating this command to a
``prereq`` command. Thus the defined constraint is recorded in the
``MODULES_LMPREREQ`` environment variable. Same approach is used for
``module unload`` modulefile command which is assimilated to a ``conflict``
command. Thus the defined constraint is recorded in the
``MODULES_LMCONFLICT`` environment variable. (see
:ref:`v42-alias-symbolic-name-consistency` section in MIGRATING document)
* Only look at loaded modules when unloading so unloading an nonexistent
modulefile does not produce an error anymore. (fix issue#199)
* Report error raised from modulefile evaluation as ``ERROR`` rather
``WARNING``, like when a conflict constraint is hit. Moreover this kind of
evaluation error is now silenced on global evaluation like when processing
``avail`` or ``search`` sub-commands.
* Record messages to report them by block on when processing a ``load`` or an
``unload`` modulefile evaluation to improve readability on these evaluating
modes that may cascade additional actions. (see
:ref:`v42-module-message-report` section in MIGRATING document)
* Foreground ``load``, ``unload``, ``switch`` and ``restore`` actions (i.e.,
asked on the command-line) now report a summary of the additional load and
unload evaluations that were eventually triggered in the process.
* Support ``del`` and ``remove`` aliases for ``unload`` sub-command like on
compatibility version. (fix issue#200 with contribution from Wenzler)
* Correctly transmit the arguments along with the command to execute on
``system`` modulefile command. (fix issue#201)
* Contrib: add ``mt`` utility script which helps to run just specific part of
the test suite.
* Introduce ``set-function`` and ``unset-function`` modulefile commands to
define shell function on sh-kind and fish shells. (fix issue#193 with
contribution from Ben Bowers)
.. _4.1 release notes:
Modules 4.1.4 (2018-08-20)
--------------------------
* Doc: fix typo on ``getenv`` command description in modulefile(4) man page
and clarify this command should be preferred over ``::env`` variable to
query environment variable value in modulefile.
* Init: fix ``bash`` and ``zsh`` completion scripts to enable Extended Regular
Expression (ERE) on ``sed`` command with ``-E`` argument (rather ``-r``) for
compatibility with OS X's and BSDs' sed. (fix issue#178)
* Handle default version sets on an hidden modulefile (were not found
previously). (fix issue#177)
* Init: fix ``ksh`` initialization script for ksh88 compatibility. (fix
issue#159)
* Install: use ``sed`` command rather ``grep`` and ``cut`` in ``configure``
and ``Makefile`` scripts. (fix issue#175 with contribution from Michael
Sternberg)
* Fix typo, tab indentation and pipe opening mode on ``createmodule.py``
utility script. (contribution from Jan Synacek)
* Check ``ModulesVersion`` value set from ``.version`` rc file to ensure this
value refers to a version name in current directory. Report error if a
nested value is detected and ignore this value. (fix issue#176)
Modules 4.1.3 (2018-06-18)
--------------------------
* Make ``setenv`` command alter ``env`` Tcl global array during ``help``,
``test`` or ``whatis`` evaluation modes. (fix issue#160)
* Doc: describe MANPATH variable special treatment on compatibility version
in diff_v3_v4 document.
* Initialize and export _moduleraw SH shell function if ``stderr`` is attached
to a terminal. Was previously checking ``stdout``. (fix issue#169)
* For ``csh`` shells, quote code generated by modulecmd.tcl to pass it to the
``eval`` shell command.
* Escape special characters when producing code to define shell aliases (fix
issue#165)
* Correct modulefile lookup when a modulefile directory is overwritten by a
module alias definition but it contains an empty sub-directory. (fix
issue#170)
* Doc: describe ``getenv`` command in modulefile(4) man page.
* Improve SH shell detection in profile.sh initialization script to use shell
variable on ``bash`` or ``zsh`` to determine current shell name. (fix
issue#173)
Modules 4.1.2 (2018-03-31)
--------------------------
* Add an example global rc file in ``contrib/etc`` directory that ensures
``MODULEPATH`` is always defined.
* Check ``HOME`` environment variable is defined on ``savelist`` and
``is-saved`` commands or raise error if not.
* Fix saving of deep module default version in collection when version pinning
is disabled: if ``foo/bar/version`` is default version for ``foo``,
collection will retain just ``foo`` (was retaining ``foo/bar``).
* Enable to save and restore collections containing full path modulefiles
eventually with no modulepath defined.
* Run ``puts`` command not related to ``stderr`` or ``stdout`` channels in
calling modulefile context to correctly get access to the targeted file
channel. (fix issue#157)
* Quote ``autoinit`` result for eval interpretation on SH-kind shells to avoid
parameter expansion to randomly occur on generated code depending on file
or directory names of current working directory. (fix RH bug#1549664)
* Ignore empty elements found in ``MODULEPATH``, ``LOADEDMODULES`` or
``_LMFILES_`` to ensure all elements in these variables are non-empty
strings.
* Raise error if loaded environment is in an inconsistent state when calling
commands requiring correlation of information from the ``LOADEDMODULES`` and
the ``_LMFILES_`` environment variables. Error raised on ``load``,
``unload``, ``switch``, ``reload``, ``purge``, ``list``, ``save`` and
``restore`` commands. May affect ``info-loaded`` or ``is-loaded`` commands
if module passed as argument to these command is specified as a full path
modulefile.
* Fix ``list`` command to process loaded modules information before performing
any content output.
* Install: adapt ``configure`` script and Makefiles to support installation on
Cygwin system.
* Detect terminal width on Windows ``cmd`` terminal with ``mode`` command.
* Improve Windows ``cmd`` shell support: error code returned, echoing text,
shell alias creation and removal, working directory change.
* Raise error when an empty module name is passed to module sub-commands like
``load``, ``display`` or ``unload``.
* Raise error when an empty collection name is passed to module sub-commands
like ``save``, ``saveshow`` or ``restore``.
* Raise error when an empty path is passed to module ``unuse`` sub-command,
like already done on ``use`` sub-command.
* Clear argument list if an empty module command name is passed.
* Fix ``module`` function definition for all shells in ``autoinit`` command to
correctly handle empty-string parameters or parameters containing
white-spaces, quotes, escape characters.
* Fix ``module`` function definition for Python to accept being called with no
argument.
* Fix parameter expansion on ``module`` function for all SH-kind shells when
quarantine mode is activated.
* Escape ``\`` character when producing R shell code.
Modules 4.1.1 (2018-02-17)
--------------------------
* Make separator lines, used on ``display`` command result for instance, fit
small screen width.
* Install: give ability to build and install Modules from git repository
without documentation if ``sphinx-build`` cannot be found.
* Install: adapt ``configure`` script and Makefiles to support installation on
FreeBSD, Solaris and OS X systems. (fix issue#147)
* Rework code generated by ``autoinit`` for sh-kind shells to avoid use of
local variables as those are defined differently through the sh variants.
(also fix issue#147)
* Init: use a default value on undefined variables in sh-kind scripts to avoid
unbound variables in bash ``-eu`` mode. (fix issue#151)
* Correctly detect terminal column number on Solaris.
* Init: fix csh init script to get compatibility with pure csh shell
* Sanitize content of ``MODULEPATH`` before using it at run-time, to make
potential relative paths absolute, remove trailing slashes, etc. (fix
issue#152)
* Check loaded modulefiles still exists before displaying statistics on them
during a ``list`` action.
* Use a specific reference counter variable name (``MODULES_MODSHARE_<VAR>``
instead of ``<VAR>_modshare``) for DYLD-specific variables. (fix issue#153)
* No error raise when updating a DYLD or LD path-like variable on OS X when
System Integrity Protection (SIP) is enabled. In this situation, these
variables are not exported in subshell context, so they appear undefined.
* Init: protect arguments passed to the ``_moduleraw`` sh function from
interfering content of current working directory. (fix issue#154)
* Install: move ``hostname`` RPM requirement to the compat sub-package.
* Start pager process only if some text has to be printed. (partially fix
issue#146)
* Ignore ``PAGER`` environment variable to configure Modules pager to avoid
side effects coming from a general pager configuration not compatible with
Modules pager handling. (fix issue#146)
* Do not blank anymore default Modules pager options if default pager is
``less`` when the ``LESS`` environment variable is defined. (fix issue#146)
.. warning:: With this bugfix release, changes have been made on the pager
setup to avoid side effects coming from the system general pager
configuration. As a result ``PAGER`` environment variable is now ignored
and ``MODULES_PAGER`` should be used instead to adapt Modules pager
configuration at run-time.
Modules 4.1.0 (2018-01-15)
--------------------------
* Extend stderr output redirection on sh-kind shells to all terminal-attached
shell session, not only interactive shell session.
* Extend shell code produced by the ``autoinit`` command to perform the same
environment initialization as done in ``init`` shell scripts (default value
set for module-specific environment variables, parse or source of
configuration files).
* Make init shell scripts rely on ``autoinit`` command to define the
``module`` command and setup its default environment.
* Fix error rendering code for Tcl shell by producing a call to the ``error``
procedure.
* Introduce pager support to handle informational messages, using ``less``
command with ``-eFKRX`` options by default. Environment variable
``MODULES_PAGER`` or ``PAGER`` may be used to supersede default pager
command and options. ``--paginate`` and ``--no-pager`` switches enable or
disable pager from the command line.
* Install: add ``--with-pager`` and ``--with-pager-opts`` configure options to
define default pager command and its relative command-line options.
* Introduce quarantine mechanism to protect module execution against side
effect coming from the current environment definition. Variables whose name
has been put in ``MODULES_RUN_QUARANTINE`` will be emptied or set to the
value hold by ``MODULES_RUNENV_<VAR>`` in the modulecmd.tcl run-time
environment. Quarantine variable original value is then restored within
modulecmd.tcl execution context once it has started.
* Install: add ``--with-quarantine-vars`` configure option to define at build
time the ``MODULES_RUN_QUARANTINE`` and ``MODULES_RUNENV_<VAR>`` environment
variables set in initialization scripts.
* Add ``MODULES_SILENT_SHELL_DEBUG`` environment variable to disable on sh
shell and derivatives any ``xtrace`` or ``verbose`` debugging property for
the duration of either the module command or the module shell initialization
script. (fix issue#121)
* Change error code produced by modulecmd.tcl for the Tcl, Perl, Python, Ruby,
CMake and R scripting languages to return a 'false' boolean value in case of
error rather raising a fatal exception.
* Adapt module function definition for Tcl, Perl, Python, Ruby, CMake and R
scripting languages to always return a value, result of the modulecmd.tcl
run. When modulecmd.tcl run does not produce a specific status, a 'true'
boolean value is returned. On CMake, resulting value is returned though a
``module_result`` global variable.
* Spool content sent to the stdout channel with ``puts`` command during a
modulefile interpretation, to effectively transmit this content to stdout
after rendering the environment changes made by this modulefile. (fix
issue#113)
* Introduce ``append-path``, ``prepend-path``, ``remove-path`` and
``is-loaded`` module sub-commands, based on existing modulefile-specific
Tcl commands. (fix issue#116)
* Introduce ``is-saved``, ``is-used`` and ``is-avail`` modulefile Tcl commands
and module sub-commands to test availability of collection, modulepath or
modulefile.
* Raise error when a call to ``path`` or ``paths`` module sub-commands is
attempted during a modulefile interpretation. Both commands now return text
rather print text on scripting languages. An empty string is returned in
no match case instead of a false boolean value.
* Introduce ``module-info loaded`` modulefile command and its module
sub-command counterpart ``info-loaded``. This new command returns name of
the modules currently loaded corresponding to the name passed as argument.
(fix issue#3)
* Fix ``is-loaded`` command to correctly handle multiple module names passed
as argument (fix issue#138)
* Support no argument on ``is-loaded``, ``is-saved`` and ``is-used`` commands
to return if anything is respectively loaded, saved or used.
* Interpret ``module source`` command set in modulefile in ``unload`` mode
when the modulefile itself is interpreted in this mode.
* Consider a modulefile passed with name starting by ``./`` or ``../`` a full
path name modulefile, like those starting by ``/``. These kind of names are
converted to absolute path names, for instance to register them in loaded
modulefile list during a ``load`` command.
* Correlate modulefile passed as full path name (starting by either ``./``,
``../`` or ``/``) to already loaded modulefile registered with regular
module name (file name without its modulepath prefix) to prevent for
instance from loading twice same modulefile. Correlate in the same way
regular module name to already loaded full path name modulefile.
* Introduce ``MODULES_COLLECTION_PIN_VERSION`` environment variable to record
modulefile version number when saving collections even if version
corresponds to the default one. (fix issue#89)
* Fix location of ``etc/rc`` global RC file to ``@prefix@/etc/rc`` instead of
``$MODULESHOME/etc/rc`` not to depend on ``MODULESHOME`` environment
variable value.
* Strengthen argument check for ``append-path``, ``prepend-path`` and
``remove-path`` modulefile Tcl commands and module sub-commands. Raise error
if argument list is not correct.
* Fix support for the ``--delim=C`` argument form on ``append-path``,
``prepend-path`` and ``remove-path`` commands.
* Fix path reference counter handling in case path element is an empty string.
Distinguish an empty path element from a variable set empty to clear it.
* Pass multiple path elements separated by delimiter character as one string
on ``append-path``, ``prepend-path`` and ``remove-path`` commands.
* Accept multiple path element arguments on ``append-path``, ``prepend-path``
and ``remove-path`` commands.
* Introduce the ``--duplicates`` argument option to ``append-path`` and
``prepend-path`` commands to add a path element already registered in
variable.
* Introduce the ``--index`` argument option to ``remove-path`` command to
delete a path entry by passing its position index in variable.
* Provide the ability to setup a site-specific configuration sourced at the
start of ``modulecmd.tcl`` main procedure. This configuration is a Tcl
script named ``siteconfig.tcl`` which enables to supersede any Tcl
definition made in ``modulecmd.tcl``. Location of this file is controlled
at configure time with the ``--etcdir`` option.
* Add the ability to handle paths containing reference to environment variable
in ``MODULEPATH``. When these kind of paths are used by ``module`` command,
the variable references are converted to their corresponding value or to an
empty string if they are not defined.
* Enclose value set to environment variable on Tcl within curly braces rather
double quotes to protect special characters in it from interpretation.
* Correctly parse ``.modulespath`` initialization file to handle lines without
any ``#`` character or to handle files with no content to extract.
* Re-introduce the ``--enable-versioning`` configure option, which appends
Modules version to installation prefix and deploy a ``versions`` modulepath
shared between all versioning enabled Modules installation. A modulefile
corresponding to Modules version is added to the shared modulepath and
enables to switch from one Modules version to another.
* Fix removal of CMake generated temporary script file by stripping newline
character from script file name.
* Add ``MODULES_CMD`` environment variable to expose path to the currently
active module command script. This variable is set at initialization time.
* Introduce ``modulecmd`` wrapper script, installed in binary directory, which
executes the active module command.
* Fix modulefile Tcl interpreter reset when handling list variables. (fix
issue#145)
* Introduce 'module-virtual' modulefile Tcl command to associate a virtual
module name to a modulefile. This module can be located with its virtual
name and the associated modulefile is the script interpreted when loading,
unloading, etc.
* Resolution of relative paths occurring during a modulefile interpretation to
target a modulefile or a modulepath now takes the directory of the currently
interpreted modulefile as the current working directory to solve the
relative paths.
.. _4.0 release notes:
Modules 4.0.0 (2017-10-16)
--------------------------
Starting with this release, modules-tcl has become Modules. The following
changes describe the differences with last modules-tcl release (1.923). To
learn about the changes between this release and last Modules 3.2 release,
please see the :ref:`MIGRATING` document.
* Relax constraint on command-line argument position so options and
switches can be passed either before or after command name.
* Report ``unsupported option`` warning rather stop on error when
compatibility-version specific command-line switches are passed (
``--force``, ``--human``, ``--verbose``, ``--silent``, ``--create``,
``--icase``, ``--userlvl``).
* Keep empty ``module load`` line in shell configuration files after running
the ``initrm`` or ``initclear`` commands.
* Always return the value of ``tcl_platform(osVersion)`` for ``uname release``
* Optimize code output, for Perl to only return ``1;`` once for a no-operation
situation and for Python to not ``import os`` when there is only an error
to render.
* Use value of system command ``uname -n`` for ``uname nodename``.
* Add support for CMake *shell*
* Ignore ``/`` character used as suffix in modulefile name passed on command
line.
* Rename Perl initialization script in ``perl.pm`` and Python in
``python.py``.
* Add support for Ruby *shell* (with contribution from Tammo Tjarks)
* Add support for R *shell* (with contribution from Roy Storey)
* When a *default* is set for a given module name, target modulefile can
be referred on as *modulename/default* in addition to just *modulename*.
* Locate symbolic versions on ``avail`` command even these symbols are set
over a module alias or another symbolic version. In this situation the
symbol spread along the resolution path until reaching a modulefile.
* Define a more standard shebang on modulecmd.tcl script.
* Determine modulefile corresponding to given module name using the loaded
context only on ``unload`` situation.
* Enable to unload *mod/dir/subdir/vers* when unload of *mod* or *mod/dir*
asked. Was previously working only if deep module to unload was also the
default version for these root names.
* Make -l/-t switches mutually exclusive. Last switch mentioned on the
command-line is honored.
* Output parsable modulepath header when -l/-t switches are enabled.
* When searching for a module in a given modulepath directory, if a module
alias or a symbolic version matches searched module but the target of
this alias or symbol is not found in current modulepath directory,
search for this target restarting search from the first modulepath in
list to ensure modulepath priority.
* Solve aliases or symbolic versions looking for all modulepaths on ``search``
and ``paths`` commands. Was previously solved if their target was found in
same modulepath directory.
* Add support for hidden *dot* modulefiles. A hidden modulefile does not
appear in case of wild search, it is only returned when search is about
its exact name.
* No table header print in --long mode on an ``avail`` command if no result
are returned.
* Add blank line between displayed list of elements, for instance between
modulepath content on ``avail`` command.
* Improve readability of error messages encountered during modulefile
execution by putting Tcl error message first after the ``Module ERROR``
prefix.
* Do not exit immediately when an internal error occurs in currently
interpreted modulefile. Consider this interpretation as failed and
continue to proceed the other modulefile arguments.
* When multiple modulefiles are passed on ``display``, ``help`` and ``test``
commands only output one separator line between 2 interpreted modulefiles.
* Fix environment settings stack handling issue when restoring stack after
a failed attempt to load a modulefile in a modulefile.
* Failed attempt to load or unload a modulefile within a modulefile now
leads to this upper modulefile load or unload failure. Previously upper
modulefile were loaded respectively unloaded even if its dependent
sub-modulefile failed to load or unload.
* During a ``switch`` command, if the unloading part fails the loading part
will not be tried. Unloading part fails if module to unload does not
exist or its unload interpretation raise error.
* Init: use ``module source`` rather shell command ``source`` to load modulerc
system configuration in sh-kind, csh-kind and fish shell init scripts.
* Install: transform configuration options to bind to an existing
compatibility Modules version into option (--enable-compat-version) to
build and install this compatibility version along with main version.
* Init: adapt initialization scripts to handle both main and compatibility
version. By default a shell script enables main version and if the
environment variable MODULES_USE_COMPAT_VERSION is set to 1, the
compatibility version is enabled instead of main version.
* Install: import from compatibility version and install ``add.modules``
and ``mkroot`` utility scripts (scripts developed by R.K. Owen).
* Install: update RPM spec file to handle compatibility version as a
``compat`` sub-package.
* Add completion script for Fish shell (contribution from BEFH).
* Doc: extend content of diff_v3_v4 to details all noticeable changes
between v3.2 and v4.0.
* Doc: introduce MIGRATING guide to learn the major changes when moving
from v3.2 to v4.0.
* Fix ``list`` command when full pathname modulefile is loaded (fix bug#132)
* Install: handle version number though git tags in scripts, documentation
and RPM spec file.
* Doc: migrate documents from POD format to reStructuredText to benefit from
Sphinx documentation framework and Read The Docs publishing capabilities.
Above changes describe the differences with modules-tcl release 1.923. To
learn about the changes between Modules 4.0 and last Modules 3.2 release,
please see the :ref:`MIGRATING` document.
modules-tcl-1.923 (2017-07-20)
------------------------------
* Fix ``aliases`` command when a global or user RC file is set.
* Find and solve global or user RC aliases and symbolic versions on
``search``, ``whatis`` and ``paths`` commands.
* Do not look at currently loaded modules to resolve the target of a module
alias.
* Rework default and latest versions search on ``avail`` command. Correct
display when at a given level a sub-directory element is last element in
directory among modulefiles. Previously sub-directory was printed but
last file among modulefiles was also printed (2 latest versions at the
same level). A directory tagged "default" does not appear anymore in
default listing result as its content (the default version found in that
directory) will be displayed.
* When an alias is set and overrides name of an existing directory, take
this alias into account for default and latest choice and ignore
directory content.
* Bad default set will lead to no result displayed for the corresponding
module in case of default ``avail`` display.
* Correct inclusion of aliases in output result when these aliases are not
part of the exact same module path than module path of the search.
* Rewrite existing shell initialization file with initadd, initprepend,
initswitch, initrm and initclear commands rather than writing a new
file then copying this new file to replace the existing initialization
file. In addition only re-writes shell initialization file if its content
need to be altered.
* Raise an error on initadd, initprepend, initswitch, initrm and initclear
commands when no ``module load`` line are found in shell initialization
file.
* Normalize error messages for the various collection-related commands
when collection cannot be accessed.
* Cleanup existing reference counters of a path list variable when this
variable is altered by a ``setenv`` or an ``unsetenv`` command.
* Init: do not pollute tab-completion with moduleraw command. (Bert Wesarg)
* Make use of the same Tcl interp for each modulefile interpretation and
use another one for each modulerc (but the same for each modulerc). By
doing so we proceed like on C-version where same interpreter is used
across modulefile or modulerc interpretation. Huge performance
improvement is achieved with this change on commands making intensive
use of interp like ``avail``. Interpreter state is reset from one
interpretation to another: the initial variable and procedure state is
restored before each new interpretation to avoid spread of definitions
from one interpretation to another. Also in case of nested interpretation
each interpretation level has its own interpreter so a module loaded by
another does not influence the interpretation of the module loading it.
* Improve performance of aliases and symbolic versions resolution by
computing these resolution at definition time. As a consequence
resolution loop are not registered anymore and produce an error message
when spotted not at display time.
* Reduce number of ``access`` system call by trying access to modulefile
when reading the content of a modulefile directory rather testing access
before trying it.
* No error raise on empty argument list for load. To cope with initadd
behavior that requires at least an empty ``module load`` line in startup
files. (fix SF bug#88)
* Fix initadd to handle load line without trailing space. Was previously
expecting load directive to be written "module load " to get a match.
With fix, ``module load`` line will also be matched.
* Like C-version catch raised error when break or continue are called from
outside of a loop to handle them as when they are called from modulefile
main body. (fix SF bug#87)
* Return error on ``module use`` command when an empty path string is
provided rather ignoring it.
* Workaround ``min`` and ``max`` functions and ``lreverse`` procedure for
correct operations under Tcl version 8.4.
* Install: add --with-tclsh configure option to give the ability to choose
the Tcl interpreter shell to setup in initialization scripts.
* Handle error raised from the ModulesDisplay, ModulesHelp and ModulesTest
procedures in the same way than for the evaluation of the modulefile
content. An error occurring during the evaluation of the modulefile
content will lead to no evaluation of the ``display``, ``help`` and
``test`` command specific functions.
* Remove ``debug`` module command
* Doc: describe ``path``, ``paths`` and ``autoinit`` module command.
* Correct use of xrdb tool when not installed in default path.
* Fix ``init*`` module commands to behave more like C-version and document
remaining differences in diff_with_c-version.
* Init: make ``sh`` init script closer to POSIX specification to support sh
flavors different than Bash or Zsh like Dash.
* Fix column-mode display for very short width terminal.
* Install: introduce an ``install`` non-regression testsuite which is
triggered by the ``make testinstall`` command and checks modules-tcl
installation is operational.
* Init: fix modulerc load test on ``fish`` init script.
* Init: fix interactive shell test on ``sh`` init script.
* Install: add --enable-example-modulefiles configure option that install
by default some modulefiles provided as example in the system modulefiles
directory.
* Install: when uninstalling, do not remove modulefiles directory if it is
not empty.
* Add completion script for Zsh shell.
* Add ``module test`` command to trigger when called execution of a
ModulesTest procedure in target modulefile following same kind of
mechanism than ``module help``.
modules-tcl-1.832 (2017-04-29)
------------------------------
* Fix ``getenv`` sub-command to correctly return environment variable value.
* Clarify in man-pages display of module alias and symbolic version-name on
``avail`` command and management of file access issue when locating
modulefiles.
* Distinguish access issue (permission denied) from find issue (cannot
locate) when trying to access directly a directory or a modulefile as
done on ``load``, ``display`` or ``whatis`` commands. In addition on this
kind of access, not readable .modulerc files are ignored rather producing a
missing magic cookie error.
* When mode is set to unload, ``module load`` commands in modulefile are
interpreted as ``module unload`` commands. To guaranty correct behavior
regarding requirements, the module list passed to the load command is
reversed to unload the modulefiles in the reverse order than they have
been loaded.
* Correct ``display`` command to only report module commands set in
modulefile and not those set in the various .modulerc on the path toward
this modulefile.
* Fix bash and tcsh completion scripts to eliminate symbolic version names
from ``avail`` command result.
* Improve ``avail`` command when a symbolic version-name is passed as
argument to return the modulefile target of this symbolic version-name.
* When looking for an implicit default in a directory, now a module alias is
taken into account so it can be returned as the last element in it
(highest numerically sorted version).
* Fix ``list`` command to correctly display the ``default`` tag along loaded
modules when set via a .version file.
* Fix long output of ``list`` command to display the symbolic version-names
associated to each loaded module if any.
* Improve ``avail`` command to return alias module when an alias name is
passed as argument.
* On a ``--default`` listing, a modulefile does not appear anymore if a
directory is set default at the same level. On a ``--latest`` listing, a
directory does not appear anymore if set default but not the latest.
* Read modulerc and validate its header in a single open/read/close sequence
instead of two in order to reduce to number of IO operations during an
``avail`` command.
* Drastically reduce grid size computation time which removes overhead when
displaying module avail results in column-mode.
* Translate module name to currently interpreted module name when name
correspond to the last part this interpreted module only in case of
symbolic version-name or alias resolution.
* Avoid resetting regular path (/usr/bin) or manpath (/usr/share/man) when
switching from Tcl to C version in switchml utility.
* Raise error on x-resource if DISPLAY environment variable is not set.
* Fix lisp init script which was broken for environment change actions.
modules-tcl-1.775 (2017-03-07)
------------------------------
* Improve README with examples, requirements, links, etc. Also update
INSTALL documentation with details on the new configure/make/make install
process.
* Add display of a release date next to the version number when calling for
``--help`` or ``--version``.
* Update diff_with_c-version document to describe the features of the
Tcl-version that are not supported on the C-version. Also state that the
diff takes C version 3.2.10 against Tcl version 1.729 as a basis.
* Introduce ``switchml`` tool, a shell function (or alias for csh or tcsh
shells) that swap currently enabled Modules version (C or Tcl) by the
other version (C or Tcl). Configure option ``--with-cver-initdir`` must be
defined to enable ``switchml`` in initialization script.
* Define a PATH and MANPATH in shell initialization scripts that point to
the defined modules-tcl installation directories.
* Give ability to generate distribution tarball from the git repository with
Makefile ``dist`` target.
* Introduce an installation process for this software following the
configure/make/make install fashion. Configure step enables to choose
installation paths and init scripts features to activate. Make step mainly
translates init scripts with the configuration set. Make install creates
target directories and copy files into them.
* Fix MODULESHOME setup in autoinit command to define it as an absolute path
and set it to the upper directory when modulecmd.tcl is located in a ``bin``
or a ``libexec`` directory.
* Correct alias and version resolution on avail command which was erroneous
in case of a modulefile holding symbols (like ``default``) and targeted by
aliases. Avail output was showing the aliases holding the symbols instead
of the modulefile.
modules-tcl-1.729 (2017-02-01)
------------------------------
* Add documentation in module(1) man page on the modulefile collection
concept and the relative ``save``, ``restore``, ``saverm``, ``saveshow``
and ``savelist`` commands.
* Add document to list the differences of the functionalities that can be
found on the C-version of the Modules package compared to the
Tcl-version.
* Improve modulecmd.tcl shebang to only search ``tclsh`` once if found in
PATH.
* Add ``module-info mode`` check against ``remove`` and ``switch`` values.
* Introduce ``module-info command`` Modules-specific Tcl command to
distinguish complex ``load`` or ``unload`` commands that cannot be
determined with ``module-info mode`` alone. For instance a modulefile can
now be aware that a ``switch``, a ``restore`` or a ``purge`` command is
currently being run.
* Enable usage of ``module-info`` Modules-specific Tcl command from a
modulerc file.
* Fix ``module-info specified`` Modules-specific Tcl command.
* No exit raise on modulefile or modulerc error during ``avail``, ``aliases``,
``whatis`` and ``search`` commands to avoid harming results from these
global commands if error exists in a few modulefiles.
* Exit with error code when a critical error is encountered when
interpreting a modulefile or a modulerc.
* Inhibit non-critical error report raised from modulefiles during ``avail``,
``aliases``, ``whatis`` and ``search`` commands to avoid error flood when
parsing all modulefiles or modulercs.
* Handle multiple lines of ``module-whatis`` Modules-specific Tcl commands
defined for the same modulefile.
* Handle multiple arguments passed to the ``module-whatis`` Modules-specific
Tcl commands. They are joined to get a single line of text.
* Return error on ``whatis`` command if searched modulefile is not found.
modules-tcl-1.704 (2017-01-20)
------------------------------
* Set path variable counter to 1 for paths without a known reference count
(was previously set to 999999999).
* Introduce ``envml`` utility which acts as an application launcher where
module commands are instantiated to setup environment before launching
the given application.
* Always register paths provided to be part of MODULEPATH environment
variable as absolute paths to get independent from the current working
directory.
* Inhibit next modulefiles interpretation with ``exit`` Modules-specific Tcl
command only if current mode is ``load``.
* Add argument to ``module-info shell`` and ``module-info shelltype`` to test
current shell or shelltype value.
* Fix use of ``default`` version-name to not consider it as a module symbol
if a modulefile is named ``default``.
* Fix path variable counters when ``:`` character is used in elements of a
path-like variable.
* Update module(1) and modulefile(4) man pages to clear content specific to
the C version of Modules and add content specific to or adapt content that
behave differently on this Tcl version.
* Fix TCLSH variable issue in Python init script.
modules-tcl-1.677 (2017-01-04)
------------------------------
* Make ``switch`` command handle a single argument. The modulefile to switch
to is the one passed on the command-line and the modulefile to unload is
assumed to be the currently loaded module with the same root name as
this modulefile specified on the command-line.
* Make ``switch`` command idempotent by always ending up with ``old`` unloaded
and ``new`` loaded, whatever the starting situation is.
* Fix ``exit`` Modules-specific Tcl command.
* Add ``refresh`` command as alias on ``reload`` command.
* Add dummy ``module-log``, ``module-trace``, ``module-user`` and
``module-verbosity`` Modules-specific Tcl commands to enable support for
modulefiles using them.
* Fix ``system`` Modules-specific Tcl command to behave like described on
the man page.
* Fix ``module list`` when module loaded with full path
* Disable ``g_force`` property by default to avoid loading a modulefile
already loaded. It also avoids path element reference counting to get
increased when the same module is asked twice for load.
* Clarify module-info ``mode`` option and set ``help`` mode on ``module help``
command.
* Clarify module-info ``flags`` and ``user`` options.
* Handle empty or separator path on ``add-path`` ad ``unload-path`` commands.
* Delete environment variable targeted by an ``unsetenv`` command on
``unload`` mode if no value has been provided along. On display mode, print
environment variable value if any has been passed to ``unsetenv`` command.
* When setting Tcl variable, enclose value within double quotes.
* Fix perl quoting style for variable set, escape single quotes rather
double quotes.
* Call ``unuse`` command instead of ``use`` command on a ``module unload``.
* Fix ``continue`` Modules-specific Tcl command.
* Add ``chdir`` Modules-specific Tcl command.
* Fix ``break`` Modules-specific Tcl command.
modules-tcl-1.655 (2016-11-23)
------------------------------
* No display of modulepath header if no module found in it.
* Remove call to ``module aliases`` on ``module avail`` command, as aliases
are now directly included in the ``avail`` results.
* Include module aliases in the displayed result of an ``avail`` command.
Also display aliases defined in a global or user modulerc file.
* Exit with error code if error occurred on display or help commands.
* Fix module-info symbols resolution.
* Better handling of .modulerc and .version files when searching for a
modulefile.
* Fix module-info version resolution.
* Fix module-info alias resolution.
* Register alias and version by the short module name and improve their
resolution to avoid loop.
* Source $MODULERCFILE/modulerc when $MODULERCFILE is dir.
* Make it so you can do ``module avail un``, wildcard ``*`` character
implied.
modules-tcl-1.632 (2016-09-06)
------------------------------
* Raise error if command does not receive the excepted number of arguments.
* Improve column-mode display to get a denser output on ``avail`` command.
* Standardize the output of Warning, Error, InternalBug and ErrorAndExit
messages.
* Add short option -d for --delim on prepend-path.
* Introduce collection target concept to distinguish between machines,
environments or domains that are incompatible with each other.
* Introduce ``saveshow`` command, to display content of saved collections.
* Improve ``save`` and ``restore`` commands to handle collection specified as
absolute or relative file path.
* Introduce ``saverm`` command, to delete saved collections.
* Enable to ``restore`` collection with multiple modulefiles specified on the
same line.
* Fix ``restore`` command when there is no module to load in collection.
* Fix ``restore`` command when collection fully rewind module paths.
* Fix ``restore`` command to preserve module path order set in collection.
* Raise error if try to save an empty environment in a collection.
modules-tcl-1.602 (2016-08-13)
------------------------------
* Add support for Fish shell.
* Import recent tests added to C-version on 10-use and 50-cmds testsuites.
* Add short option -d for --delim on append-path and remove-path.
* Fix load and implement unload x-resource.
* Fix Python code that was broken or not Python3-compliant. Fixed code is
used to define the module command, to render error and to process
x-resource.
* Always dictionary-sort (also called numerical-sort) list of modulefiles
or list of collections.
* Fix bash completion script to be compliant with bash posix mode.
modules-tcl-1.578 (2014-12-24)
------------------------------
* First release to be described in this NEWS file but it does not mean this
is the first version of modules-tcl as this Modules flavor is born in
2002.
* At this stage, modules-tcl handles a majority of the module commands and
modulefile Tcl commands available on C version.
